How to Factor the Quadratic Equation to know Variable Quantity?

An algebraic equation is one of the common math problems which include linear, quadratic and other higher degree equations. Solving out these equations is difficult sometimes due to the tough coefficient. If your kid is facing any difficulties in solving the algebra homework, then you can help by knowing the easy method for its solution. You can access the digital platform in which you just have to enter the coefficient then you can achieve the variables.

Without the graphing calculator or algebraic calculator, it is difficult to solve but it is not so. You can use the formula method or use the factors to determine the variable values. How to factor is the most common question that would come to the mind of the learner.  

Quadratic Equation

How to solve the quadratic equations?

Before solving the quadratic equation, you should understand its basics. To understand the quadratic equation, consider an example as- 2x² + 6x + 9 = 0 

A quadratic equation is written above in which x is the variable, and the number with X is coefficients and remaining one is constant. To get the math help by the calculator, you just have to fill the coefficient and constant values into the software. You can easily get the variable value which may be negative or positive. On the other hand, you can use other methods. These methods are as-

Solve by formula method 

A and B are the coefficients of   and x respectively, and C is the constant value available in the algebraic expression. Here in the equation, you have  

A= 2

B = 6

And c = 9

Now put the value into the equation, you will get,

After solving the numerical expressions, you can get two values. One is negative, and other one is positive.

By Factor method

Factor method is nothing but breaking out the expression into two parts i.e. taking out the common factor from the expression. Also, it is the simple and fast method to get the variable values. In this method, you don’t need to remember the complex formula. To better understand the factor method, you should know how to factor the expression. Consider an example to understand the factor method better and solve the quadratic algebraic equation.

2x² + 6x + 9 = 0

Follow the steps-

2x² + 2x + 3x + 9 = 0

In this step, the central part is divided into two parts

Now, you have to select the common factor out, i.e.

2x² + 2x + 3x + 3 = 0

2x(x + 3) + 3(x + 3) = 0

Take out the common factor again,

2x(x + 3) + 3(x + 3) = 0

(x + 3) (2x + 3) = 0

Now, you have two factors i.e. (x + 3) and (2x + 3)

Keep both the factors equal to zero to achieve individual values

X+3 = 0

X = -3

Again,

2X + 3 = 0

2X = -3

X = -3/2

We have two values of X which are determined by the factor method i.e. X = -3, -3/2

By this method, we do not have to face any complex calculations as faced in formula method. Here the most complex calculation is to choose the common factor. Also, you can find the simple method, but these methods are best to get the accurate answers. To check the answer, you can put the variable value into the expression. If the quadratic equations become zero, then you have right variable values.

Learn the most Basic Steps for Solving an Algebra Equation

Mathematics has been one of the most interesting subjects among the learners. There are numerous interesting topics that are available for the learners of mathematics. One of them is solving an algebra equation. There are many important concepts that need to be understood and many other methods that need to be learned in this respect. There can be many easy ways through which the beginners can become perfect in solving a linear equation. Understanding these would help the readers to get better at them. Therefore we are going to discuss some most common and interesting facts about the steps involved in solving linear equations.

Algebra Equation

Let’s understand better

Linear algebraic expressions can be said to be the equations with any common variable like “x”. However, these do not have anything complicated like x⁄y or x² . Therefore these are much easier to solve than any other equations you may have. There are no square roots or anything more; there are just simple variables and operations. So if you are looking out for such simple equations then relax for you will be able to complete your algebra homework on time.  Solving simple equations is just like the ‘fill in the block’ exercises in your early schooling years. However here you need to ascertain the exact value that will be working in place of the variable “x”.

You may get to learn more advanced methods in respect of solving these equations. The first and the most important this that you need to know in this respect is to separate the variable from the other part of the algebra equation. For this, you may also need to consider the rules of LHS and RHS. This way you will be able to bring in the answer i.e. the correct value of x. Let’s understand this with an example. For example, the problem is: 

Solve x+9 = -30

Now the main thing you need to ensure is to isolate x from the other contents in the equation. The next will be: x =  -30-9 ;

When you bring 9 to the other side in order to separate x from the equation, you need to focus on the sign change. You need to perform exactly the opposite operation in order to simplify the equation. Also, you need to consider the negative sign with 30. This is important as it will play a major role in getting the solution. The digit 9 which is added on the left side will now be subtracted when it moves to the right. So now the solution for x is simple.

x = -21

Thus it is very easy to solve linear equations. However, there are many other methods that you need to learn and can be applied to get the right answers for these equations. But this is the basic rule that you need to follow in respect of all types of equations. Therefore now you can easily try to complete your algebra homework. A bit of practice will always be the best to make you perfect for solving algebra equations without any help. Also, it will always improve your perfection.

The Order in Which Algebra Equation Should be Done

For some people, algebra is a difficult subject when it comes to master it. Besides the numbers, there are also some letters that are found in the equations. Such letters will be called variables, and they are used to represent unknown numbers.  At the beginning, it can be overwhelmed, but when you learn some concepts and practice often, you will be successful with algebra.  After knowing the basic, you can use them in everyday life and not only in doing algebra homework.

Algebra Homework

Start by understanding PEMDAS. This is the acronym on how the operation in algebra should follow one another. It stands for Parentheses, Exponent, Multiplication, Division, Addition and then Subtraction.  When you are solving any problem, you have to start on expression found within parentheses and follow up the order of the acronym and finish up with subtraction.

To solve any problem in algebra homework, you will have to base yourself on PEMDAS. Sometime, the problems may include parentheses to show the operations that have to be performed before others. Division and multiplication are at the same rank, and you can solve them in any order based from the left toward the right. This is the same for the subtraction and addition.  When you practice more, you will be able to solve more problems and much easier. When you use such order for the operation, it will be your second nature and it will not be hard to solve problems in algebra. You can work on different problems, and you will feel more confident when it comes to work on your algebra homework.

When you feel that the homework is overwhelming, you should ask someone to help you. You can ask your teacher, or you can get a tutor. You can even ask a friend who is better in algebra than you. Consider algebra like a puzzle that you have to solve. Just like the puzzle, you have to bring together different pieces. You should learn how to recognize symbols and numbers for a placeholder and ensure that you make a solution to be easier to understand.  While solving algebra problems, you need to know that if you change one side in equations, you have to do the same at the second side. When you divide, multiply, subtract or add to one side, then you have to do it at the second side.

Bring the variable at one side of an equation. If you are given algebraic expression, you will notice that they will be variables and constants. The constant is a given number while a variable is a letter which represents any unknown number. While isolating the number, you will need to subtract or add terms so that you may end up with variables at just one side. When the variable has some coefficients, you have to divide with it at both sides in order to get variables on their own. Put together all terms that looks the same so that you may simplify the problem. It helps in keeping the equation at a manageable and easy to solve the level.
