1. Difference Of a Perfect Square Problem (x2 – 16) The Difference of a perfect square has a rule that can make factoring of different perfect squares simple

2. The rule for the difference of a perfect square is (a2 – b2) (a + b) (a – b) So since our problem is (x2 – 16) x 2 is a2 and 16 is b2

3. If x2 is equal to a2then x is equal to a and if 16 is b2 than 4 is b Apply the rule of the differences of perfect squares to your problem and now it is (x + 4) (x – 4) And that is your answer.
