A flowchart is shown. At the top in the center is a box containing "GCF." Branching off of that in the second row are 3 boxes. From left to right they are labeled "2 terms," "3 terms," and "4 terms."
There is one box branching off under the "2 terms" box. It contains "a squared minus b squared. Difference of Two Squares."
There are 3 boxes branching off under the "3 terms" box. The top box contains "x squared plus b times x plus c. Leading coefficient of 1. Factors of the last term that sum to the middle term. The middle box contains "a times x squared plus b times x plus c. Leading coefficient other than 1. Factor by grouping." The bottom box contains "a squared plus 2 times a times b plus b squared. Perfect Square Trinomial." There is 1 box under the "4 terms" box. It contains "a times x plus b times y plus a times y plus b times y. Factor by grouping."
