Factor by Grouping Used when there is four terms in the polynomial to factor The object is to see if there is a common GCF between the two groups

Grouping

Factoring Perfect-Square Trinomials If the first term and the last term of a trinomial are perfect squares but there is a center term It can not be the difference of perfect squares but it may be a perfect square trinomial a2 + 2ab + b2 = (a + b)2 a2 – 2ab + b2 = (a – b)2

Sum and Difference of Cubes Just like with the Difference of Perfect Squares…….this must be a binomial. But now the 1st and 2nd terms are perfect cubes These are formulas, answer is completely factored
