10. Examples

11. Example 1 Factor ac=-30b=-7 -10,3-10 + 3 = -7 1.Multiply the a and c terms 2.Define factor pairs and sums 3.Relace b term with factor pairs 4.Factor by grouping

12. Example 2 Factor ac=6b=7 1, 61 + 6 = 7 1.Multiply the a and c terms 2.Define factor pairs and sums 3.Relace b term with factor pairs 4.Factor by grouping

13. Example 3 Factor ac= 30b=17 15,215 + 2 = 17

14. Example 4 Factor ac=72b=18 12, 612 + 6 = 18

15. Guided Practice

16. Factor ac=10b=-7 -5, -2-5 + -2 = -7

17. Guided Practice Factor ac=60b=-19 -15, -4-15 - 4 = -19

18. Guided Practice Factor ac=-30b=-13 -15, 2-15 + 2 = -13

19. Guided Practice Factor ac=30b=-11 -6, -5-6 -5 = -11

20. Guided Practice Factor ac=-16b=-5 none?
