1 Factoring Grouping (Bust-the-b) Ex. 3x 2 + 14x - 24Ex. 6x 2 + 7x + 2

2 Bottoms Up ·find ac, ac=-30 ·put ac in one column and b in the other ·find all factors that will give you ac ·find the one set that will give you b ·take the set (-2 15) and divide it by a and your variable (x) ·reduce the fractions ·write your factors by taking Bottoms Up

3 acb 10x 2 +13x-3 Bottoms Up

4 Ex. 20x 2 + 3x - 2Ex. 8x 2 - 9x - 14

5 Factor Completely and Solve Ex. 4x 2 - 25x + 25 = 0Ex. 12x 2 + 26x + 12 = 0

6 Ex. 8x 3 - 46x 2 - 70x = 0
