Difference of Two Perfect Squares

Factoring Difference of Two Squares Both terms must be Perfect Squares and have a MINUS between them Check the binomial for GCF Use two sets of parenthesis (one’s a plus, one’s a minus) Split up what it takes to make the 1st a perfect square and what it takes the 2nd to be a perfect square

Perfect Square Trinomials

Perfect Square Trinomials Whenever you square a binomial, the resulting trinomial is called a perfect square trinomial. Factoring Perfect Square Trinomials (it’s a shortcut ): a2 + 2ab + b2 = (a + b)2 a2 - 2ab + b2 = (a - b)2
