1
Factoring Grouping (Bust-the-b) Ex. 3x2 + 14x Ex. 6x2 + 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
10x2+13x-3 Bottoms Up ac b

4
Ex. 20x2 + 3x Ex. 8x2 - 9x - 14

5
**Factor Completely and Solve**

Ex. 4x x + 25 = 0 Ex. 12x2 + 26x + 12 = 0

6
Ex. 8x3 - 46x2 - 70x = 0
