11. Factor 32x3 – 32x2 + 8x by first finding the GCF, then factor the quadratic that is left. Be sure to factor completely and show your work. If this is not possible for some reason, state why. 12. Factor x2 + 9x + 14 by grouping. Be sure to factor completely and show your work. If this is not possible for some reason, state why.

13. Factor 4x6 – 16x2 using the difference of squares method. Be sure to factor completely and show your work. If this is not possible for some reason, state why.

14. Factor x2 + 16x + 64 by using the perfect squares method. Be sure to factor completely and show your work. If this is not possible for some reason, state why.

15. Factor x2 + 9 using any method you choose. Show your work. If this is not possible for some reason, state why.

16. Solve -3x2 - 9x + 12 = 0.

17. Solve x2 - x = 56
