Differences of Squares (and other even powers) ?

A square monomial is a monomial which is the square of another monomial. Here are some examples:
25 is the square of 5
x2 is the square of x
x4y6 is the square of x2y3
25x4y6 is the square of 5x2y3

How do you know if a monomial is a square? It's easy. It's a square if

1. the coefficient is a perfect square (which, by the way, means it can't be negative) and

2. all the exponents on the variables are even.

Remember that the word difference means subtraction. So here's an example of a difference of squares:

25 - 4x2.
(Notice that 25 is a perfect square, and so is 4x2.)
Factoring a difference of squares is easy.

Step 1: Rewrite the two terms as squares of something.
25 - 4x2
= 52 - (2x)2
Step 2: Apply the rule a2 - b2 = (a -b )(a + b).

= (5 -2x)(5 + 2x)
