**Factorization of binomial expressions expressible as the difference of two squares**Whenever you have a binomial with every term being squared (having an exponent of 22), & they have subtraction as the middle sign, you must have the case of difference of two squares.

**Difference of Squares**

The difference of two squares is a theorem that describes that if a quadratic equation can be written as a product of two binomials in which one exhibits the difference of the square roots & the other exhibits the sum of the square roots. This theorem is not applicable to the sum of squares.

**Formula of Difference of Squares**

The difference of square formula is an algebraic form of the equation that is used to describe the differences between two square values. A difference of squares is described as a2 – b2 where the 1^{st} & the last term are referred to as perfect squares.

Factoring the difference of the two squares gives a2 – b2 = (a + b) (a – b)

**Steps to Factor Difference of Squares**

(i)Check if the terms have the greatest common factor (GCF) & factor it out. Must

include the GCF in the final answer

(ii)Determine the numbers that will generate the same results & apply the formula of a2– b2 = (a + b) (a – b) or (a – b) (a + b)

(iii)Check whether the remaining terms can be factored any further.

For instance: Factor 64 – x2

Solution: The square of 8 is 64, so we can rewrite the expression as 64 – x2 = (8)2 – x2

Now, apply the formula a2 – b2 = (a + b) (a – b) to factorize expression = (8 + x) (8 – x).
