Factor each polynomial completely.

Both terms are perfect squares The operation is subtraction The terms in each binomial are the square root of the terms in the problem One binomial is addition and one binomial is subtraction Difference of 2 Squares a² – b² = (a + b)(a – b)

Factor each polynomial completely.

Sum / Difference 2 Cubes a³ – b³ = (a – b)(a² + ab + b²) a³ + b³ = (a + b)(a² – ab + b²) Both terms are perfect cubes Operation may be addition or subtraction The terms are a binomial and a trinomial Rule: Cube root of each term Rule: Square / Opposite Product / Square

Factor each polynomial completely.

1 st and 3 rd terms are perfect squares The middle term is twice the product of the square roots of the perfect square terms Perfect Square Trinomials a² + 2ab + b² = (a + b) ² a² – 2ab + b² = (a – b) ²

The terms in the binomial are the square roots of the perfect square terms in the problem The operation is the same as the middle term Perfect Square Trinomials
