1. Chapter 8 review Algebra 8

2. Problem #1 • Factor the monomial completely.

4. Problem #2 • Find the GCF.

6. Problem #3 • Find the GCF.

8. Problem #4 • A landscape architect is designing a stone path 36 inches wide and 120 inches long. What is the maximum size square stone that can be used so that none of the stones have to be cut?

9. ANSWER #4 • GCF: • The maximum size square is 12in x 12in

10. Problem #5 • Factor.

12. Problem #6 • Factor.

14. Problem #7 • Factor.

16. Problem #8 • Factor.

18. Problem #9 • Solve.

19. ANSWER #9 • Set each factor = 0 then solve.

20. Problem #10 • Solve.

21. ANSWER #10 • Bring 3x to the other side, factor, then set each factor = 0 to solve for x.

22. Problem #11 • Factor.

23. ANSWER #11 • Leading coefficient is 1 (a=1) so break down the constant.

24. Problem #12 • Factor.

25. ANSWER #12 • Leading coefficient is 1 (a=1) so break down the constant.

26. Problem #13 • Solve.

27. ANSWER #13 • Leading coefficient is 1 (a=1) so break down the constant.

28. Problem #14 • Solve.

29. ANSWER #14 • Leading coefficient is 1 (a=1) so break down the constant.

30. Problem #15 • Factor the trinomial, if possible. If the trinomial cannot be factored, write prime.

31. ANSWER #15 • Factor out GCF. • Leading coefficient is not 1 (a>1) so make a MAMA chart.

32. Problem #16 • Factor the trinomial, if possible. If the trinomial cannot be factored, write prime.

33. ANSWER #16 • Leading coefficient is not 1 (a>1) so make a MAMA chart.

34. Problem #17 • Solve each equation. Check your solutions.

35. ANSWER #17 • Leading coefficient is not 1 (a>1) so make a MAMA chart.

36. Problem #18 • Solve each equation. Check your solutions.

37. ANSWER #18 • Bring over 24 to the other side. • Factor out GCF • Leading coefficient is not 1 (a>1) so make a MAMA chart.

38. Problem #19 • Factor each polynomial.

39. ANSWER #19 • Factor out GCF. • Now you have difference of two perfect squares so break down further.

40. Problem #20 • Factor each polynomial.

42. Problem #21 • Solve by factoring. Check your solutions.

44. Problem #22 • Solve by factoring. Check your solutions.
