Example for Expression Factoring Calculator

Introduction:
                        Expression factoring is defined as the multiplication of the two expressions and get another expression is called factoring calculator. The factoring calculator denotes the expression multiplication of each variable in the terms.
For Example:
              x2 – x – 2 
            (x + 1) (x – 2)
Two expressions has multiplied together you can get the original expression of the given function.

Examples for Expression Factoring Calculator:

Solve the expression by factoring:
            x2 +6x + 9
Solution:
Given that x2 +6x + 9
Given expression have constant 9.
Separate the 9 into two factors
 9 = 3 * 3
 6 = 3 + 3
 So the expression will be x2 + 3x + 3x + 9
                                    Take the x out from the first two variables.
                                           x(x +3) + 3x + 9
                                    Take the 3 as a common from the next
                                           x(x+3) +3(x + 3)
                                                (X+3) (x + 3)
The solution is (x+3) (x +3).
