• Perfect Square Trinomials - (ax)2 + 2abx + b2.  A perfect square trinomial is a quadratic that can be

factored into two identical binomials that take on the form of (ax+b)2 or (ax+b)(ax+b).

• Difference of Perfect Squares - a2 - b2.  The difference of perfect squares is when a number is

squared and then subtracted by another squared number and can be factored as (a-b)(a+b).
