What are algebraic equations? Learn how to solve them

Algebraic equation is also known as polynomial equations. A polynomial expression is made up of constants and variable, combined using mathematical operators. When a polynomial expression is equated to some constant value, it becomes polynomial equation. To understand this in simple terms, go through the following example.
x²-5x+6
Is a polynomial equation, here x is a variable, 5 and 6 are constant and mathematical operators used are addition and square, but
x²-5x+6=0 is a polynomial equation or algebraic equation because it is equated to a constant (in this case zero).
The general form of a polynomial equation is
As one can notice the power f x keep on decreasing. The above equation is called a polynomial degree of order n.

What is degree of polynomial?
Degree of a polynomial is the highest power of variable. Degree of a polynomial is always a non-negative integer.
Depending upon the degree of polynomial, polynomial may de defined as quadratic equation, Linear equation or constants.
To be very particular a polynomial equation of degree 2 is called quadratic equation, polynomial equation of degree 1 is called linear equation and polynomial equation with degree of polynomial zero are nothing but constants values.
In this module we will focus on quadratic equations
The general form of a polynomial equation is ax²+bx+c= 0
Here,
·         a is the coefficient of x2
·         b is the coefficient of x And
·         c is the constant term
To solve quadratic equations there are three methods available, they are:
·         factorization
·         completing the square method
·         using quadratic formula
Let us see each method is detail.
Factorization method
In this method the quadratic equation is decomposed into 2 factors. (What are factors? Factors are those values, which if substituted into the original equation, then it result out to zero. ) for example in our example, x²-5x+6 =0 the equation can be written in the form, (x-2) (x-3)=0 . If one opens the bracket and multiply the terms then we get the original equation x²-5x+6 . Therefore (x-2) (x-3) are known as factors of the equation x²-5x+6 =0

How to find factors of any quadratic equation?
To find the factors of any quadratic equation, follow these steps:
Step 1 Decompose the middle term, i.e., the terms containing the x and it coefficient into 2 parts, such that the product of those two terms should be equivalent to the product of x2 term and the constant term. Also, the summation of those decomposed two terms should give back the original middle term.
Step 2 Take common out from the first two terms, and from second two terms in such a way, that you get common factor among both these terms.
Step 3 Again take the common factor out, and then you are left with 2 final factors of the original equation.
If the above mentioned steps are not clear to you, go through the following steps:
Let’s start with
x²-5x+6 = 0
Now let us write 5x as -2x -3x
x²-2x -3x+6 =0
This is so because, product of (-2x) and (-3x) is (+6x2), which is same as product of (x2) and (6), i.e., (6x2), the product of x2 term and constant term.
Now, take x common out from x2 and (-2x) and (-3) common out from (-3x) and (6)
The equation becomes x(x-2)-3(x-2)=0
Now take (x-2) common out
 (x-2) (x-3)= 0
These are the factors of the original equation x²-5x+6=0
 

The values of x in this case would be 2 and 3.

How to change Decimal into Fraction

Math is not something easy for most people. There are some concepts that are difficult, and one of them is that you can change the fraction to the decimal and it may be confusing according to the fraction.   Even if you are using the calculator or do this on your own, there are different methods that you may follow if you want to turn the fraction into decimals.  
Know the available terms: every number in the fraction comes with its own names. A top number in the fraction is known as the numerator, and the bottom number is known as the denominator. The fraction does express the idea of a numerator, and it is divided by a denominator.  The example is three over four which is 3/4, and this means that it is 3 that should be divided by a 4. You may use the idea in changing fraction in decimals.    
Rewrite the fraction: you should start by changing the decimal in the fraction and to rewrite the fraction as the workable math problem. 

  
Solve the problem:  you should start by solving x if it is found in the problem before you can change the fraction in the decimal.  If the fraction is a number of itself, then the answer is going to be 1.  

Solving the fraction using remainders; you can find simple fraction which has the remainders and then divides them.  When there is a remainder, then you should add zero after the decimal.

-        Whenever it is possible, you have to solve the division problems and make sure that there is no remainder.  
-       Keep track of the place where the decimal has to be.  You may get wrong decimal since you may have removed the place where the decimal point has to be.
Solving fraction that has repeating decimal; sometimes the fraction cannot be divided well into other numbers.  If this takes place, you will have the repeating decimal.  This will lead to the remainder, and the decimal number will continue to repeat itself.
-       When the remainder is the same, even if you continue to add zero, the same remainder will be the same, and the same number you are getting will continue to come
-       In writing the answer, you should cut off decimals at the amount of the places which are needed for the assignment. You may put the straight line over the number that repeats itself to show that it is the same that comes back.

Changing of the complicated fraction; you can find some fractions that are more complicated compared to others since it takes more time in dividing them. You should use the remainder until it gets finished.

Solving the irregular fraction; the complicated fraction has a definite decimal answer. You can find some fractions that have always the remainder. Contrary to repeating decimal, the decimal will not have pattern.  Even if you may continue, you will still have the remainder so you should write only the decimal up to the required number.

Where to get Algebra Help

If you want algebra help, you can get it from worksheets, calculators, and lesson that have been developed to assist the students or teachers while learning or teaching algebra. 

Lessons: you can explore the lessons available on algebra such as simplifying, equation or factoring among others.

Calculators: you can use calculators if you are having problems in solving some equation. The calculator can show the best answer with the step by step solution on how you may solve the same equation.  With these calculators, the students had been able to solve over 15 million equations. However, the calculators are not meant to solve the equation only since they can help you to know step by step method that you can use while solving the problem at hand.

Worksheet: If you need practice with some new problems, then you can use the worksheet section. You may compare the answers against the answer keys, and then you may see step by step solution for every problem.
If you still need to get extra help, you can contact a math tutor or an algebra tutor online, and he will be ready to help you to out.

Most of the students do not like the idea of having to learn algebra while in high school and in college since they do not think that they may use it in their everyday life.  However, learning algebra helps in solving financial problems, business solution, and even everyday dilemmas. If you want to succeed with algebra, you have to start by understanding the situations that require formulas with concepts. The best part is that the common life problems require highly recognizable technique and they are widely applicable. You can use the quadratic equation if you want to find the minimum or the maximum of a certain value. You can then use the linear equation if you want to determine which type of the service you are able to afford if the service does involve the flat fee and the rate. Use two linear equations in the system if you wish to compare two different plans and you want to figure out the turning point that makes a plan to be better compared to another.

You can use exponential equation if you want to represent or to solve the saving on the loan situation. If you are not able to know which type of the equation involved, you may attack the situation using real-life situation and convert the idea into numbers. If you are writing the equation starting from your words, you should not copy down each part of problem or orders. You should consider numbers and the unknowns and how they can relate from one to another. The values may be expected to be smaller or larger. You may use common sense if you are writing out an equation. If you are not sure, you can draw a graph or a picture. This can help in brainstorming how to use the equation which may fit better the situation.

The increase of the mean grade leads to recognition of your performance by the school fraternity. These can make sure that you have a great time in school time. Most of the student can like spending a lot of their time with you to be able to learn from your skills.

Increased reward
Rewarding the best students in the school motivates the rest of the school to work hard. The rewarded students are also motivated to make sure that they can increase their final grades in the school. Most of the educational institutions have the special day where they reward the best student in most subject and units. Being the best in the mixed fraction calculations can make you the best students in most subjects and units. These can make sure that you receive most gifts and rewards from the school. The parents and guardians enjoy seeing their kids performing well in their academic works.

Simplifies life
Again, most people have to manage big empires and business when they are adults. It can be straightforward when they can handle most of the calculation in the business. Ability to handle the mixed fraction in the school can assure that your future can be great. You don’t need to hire most employees to help you with the calculation in your company. These can make sure that your empire can develop with no time.

Encourage asking questions

Mathematics has challenges that at times it is difficult to ask for explanations. Doing the mixed fraction can make sure that you discover the areas that you have problems. It can be easy to approach a teacher when you know the specific areas where you need assistance. Again a simple explanation can make sure that you can understand the whole content. Most of the students can also approach you when they need your help in most of the subjects. The teachers can use you to explain most of the cases to other student or teach others. Most of the students fear the teachers thus they can understand well when their students take the opportunity to explain to them.

How to Simplify Radicals

If you want to learn how to simplify radicals, you should know how you can convert the expression with the rational exponents, how to convert expression using rational exponents to the radical equivalent, using of the exponents law in order to simplify the expression with the rational exponents  or using rational exponents in order to simply radical expression.
Most of the time, the square root has to be written by using a radical sign. However, it can also be represented by using its root. You may use the rational exponents and not the radical. The rational exponent is the exponent used as a fraction. The example is instead of writing the root of 4, it will be written 41/2.

You may have to get used to raising the rational exponents; however, the rational exponents may help in simplifying the problem.  You should be aware of which relationship found between radicals, exponents and fractional.



Fractional and radical exponents are the alternative way that someone can use to express something.  You may have seen how square roots may be expressed as exponents at the power of just one half.

When it is cube roots, then the cubing of the number, it will raise the power up to three.   The exponent is used to refer to the quantity which is found at the left if the grouping of the symbol was used.  Like you may write the expression using the rational exponent with the radical expression, it is possible to express the radical expression by the use of the rational exponents.

The rational exponents using a numerator which is different to one: All the numerators for the fractional exponents, a person may use the fractional exponents which have the numerator which is not 1 in order to express the roots.

In order to write the radical by the use of the fractional exponents, power at which the radical had been raised, it will become the numerator, and the root will become the denominator.

The rational exponents have been subjected to same rules as it happens with other exponents and they do appear in their algebraic expression.  The simplification method can give different results according to which context of a problem.  It will be easier in using one method and not the other.  It is possible to simplify the expression faster by the use of the rational exponents compared to the pull out method.

Another alternative method is working on simplifying the radical using the factoring.   For a complicated expression of two variables, the racial and the fraction, it is good to know the steps to use when it comes to fractional exponents, and it may help the user to simplify it more.  Depending on the type of questions, the user will use negative exponents, fractional exponents and the rule of the exponents so that they may simplify the entire expression.

Rewriting radicals by using fractional exponents, it may be useful in simplifying the radical expression.  While working with the fractional exponents, you should remember that fractional exponents are subjected to the same rules like other exponents if they appear in the Algebraic expression.

Why Students Should Use Radical Calculator

A radical calculator is a tool which can be used in order to find the nth root of a given number. The n value may be a negative or a positive integer, or it may be decimal.
If the students are looking to get a square root of a certain number, they will do this manually, and they are going to get the square root of a certain number.  Another option is that the students may turn to the calculator and they can get the square root there.   The regular calculator may be used by students only in order to find the square root of the number, and this is the 2nd root. When the students are looking on to get the cube root of or the 4th of the power of a base, they will not be able to do with the normal calculator.
When the person is looking the base of the fraction such as 3/4, it can be difficult in finding that value using a regular calculator or manually. The students should apply the logarithm so that they may get the value of one where the power of the base is 3/4.  When the students choose to use the logarithm, it can take longer in order to get the results where the power will be 3/4.

If the students are doing long problems in the math, they would have to take a long period in concentrating on how they can get the idea in solving the problem.  Sometime, they should get the value of which the power itself is the fraction. When it comes to solving lengthy problems by doing above work like the part of the problem, it will be annoying.  In this case, the student may turn to the radical calculator found online in order to get the n root of the number and here the n is a negative and positive integer and sometimes it can be decimal.
If someone wants to solve the word problem with math, the first step is to know how such problem should be solved.  In certain situation, the students may have to find nth root of the number. When thinking about how they should solve such questions, they may not be willing to spend too much time working on these problems alone.

If there is a need to find the n root, then students will make a mistake if they are not careful about how they find such root. To avoid the problems, it is good for the student to use the radical calculator that has been programmed in order to get n and to continue in order to get the complete solution. Through the use of the online calculator, the student can find the way of solving the problem much easier. 

The radical topic is given on the school level math, and they should solve too many problems on this topic.  Sometime the students may do an exercise, but they may not be aware if the questions they got are correct or not. This is the time that radical online calculator can be used in order to verify the answer.
