12. x3 - 12x2 + 48x - 64
A (x - 4)(x + 4)2
B (x-4)3
C (x + 4)3
D (x + 4)(x - 4)2
E (x - 4)(x2 + 2x + 1)
F cannot be factored

ans:B (x-4)3
C
13. -2w4 + 1250
A -2(w2 + 25)
B (w - 5)(w + 5)(w2 + 25)
C -2(w - 5)(w2 + 25)
D -2(w - 5)(w - 5)(w2 + 25)
E -2(w - 5)(w + 5)(w2 + 25)
F cannot be factored

ans:E -2(w - 5)(w + 5)(w2 + 25)
14. a9 - 1
A (a3 - 1)(a6 + a3 + 1)
B (a + 1)(a6 + a3 + 1)
C (a - 1)(a2 - a - 1)(a6 + a3 + 1)
D (a - 1)(a2 + a + 1)(a6 + a3 + 1)
E (a3 + a + 1)(a6 + a3 + 1)
F cannot be factored

ans:A (a3 - 1)(a6 + a3 + 1)

15. a4 + 3a3+ 27a + 81
A (a2 + 3a - 9)(a2 + 2a + 3)
B (a - 3)(a2 + 3a + 9)
C (a + 3)(a2 + 2a + 3)
D (a + 3)(a2 + 4a + 9)
E [(a + 3)2](a2 - 3a + 9)
F cannot be factored


E [(a + 3)2](a2 - 3a + 9)
