Factoring Differences of Squares. Remember, when factoring, we always remove the GCF (Greatest Common Factor) first. Difference of Squares has two terms.
 1. Square the first term.  2. Double the product of the two terms.  3. Square the last term.  Ex:  (2x – 1) 2  4x 2 - 4x + 1 Perfect square trinomial.
Solve Notice that if you take ½ of the middle number and square it, you get the last number. 6 divided by 2 is 3, and 3 2 is 9. When this happens you.
