Let us understand it step by step by taking an example:

**Step 1:**First of all we have to simplify the given expression. For example: Assume that we are given a polynomial expression 2x

^{2}+ 2x

^{2}- 10 – 6. Now we have to simplify it as 4x

^{2}– 16.

**Step 2:**Examine the Integer value in equation. The integer in equation is a perfect Square. In this equation integer term is 16 which is a perfect square. If it is possible to write it in terms of exponent then we will write it. Here we can write 16 in terms of exponent as 4

^{2}.

**Step 3:**Now we will review the equation and will check that if it is making a difference of two perfect square terms which means that this equation is representing a subtraction of two perfect square terms. Now we will Set this equation in format of subtraction of two square terms that is a

^{2}– b

^{2}.

**Step 4:**Now we will factorize this equation using the difference of two square formula that is (a + b)(a - b). Equation 4x

^{2 }– 16 will be written in factorized form as (2x + 4)(2x - 4).
