Include in your solution that the product of two binomials gives back the original trinomial. Rewrite bx as a sum of the two factors. Web factoring trinomials (a = 1) date_____ period____ factor each completely. Grouping steps for factoring “hard” trinomials decide your signs for the parentheses. 1) 3 p2 − 2p − 5 (3p − 5)(p + 1) 2) 2n2 + 3n − 9 (2n − 3)(n + 3) 3) 3n2 − 8n + 4 (3n − 2)(n − 2) 4) 5n2 + 19 n + 12 (5n + 4)(n + 3) 5) 2v2 + 11 v + 5 (2v + 1)(v + 5) 6) 2n2 + 5n + 2 (2n + 1)(n + 2) 7) 7a2 + 53 a + 28 (7a + 4)(a + 7) 8) 9k2 + 66 k + 21 3(3k.
