c) f (x) = (x-2) (x 5) (x 8) d) f (x) = x ^ 3-11x ^ 2 14 x 80

3.) Which of the following as factors is a polynomial with zeros at 0.2 and 4?
a) f (x) = x (x-2)) (x-4) b) f (x) = x ^ 3-6x ^ 2 +8 x
c) f (x) = x (x +2) (x 4) d) f (x) = x ^ 3 +6 x ^ 2 8

4.) What is the multiple zero and the multiplicity of f (x) = x ^ 3 +10 x ^ 2 x 25?

5.) Express (1-x) (x +2) (2x 2) standard form.

6.) Division of the synthesis and use the remainder theorem to find that P (a).
P (x) = x ^ 4 + x ^ 3-5x ^ 2 +9 x-6 = 3

7). Divide using synthetic division. (x ^ 4 15 x ^ 3-77x ^ 2 +13 x-36) / (x-4)

8.) Division of the use of synthetic factor y = x ^ 3 +3 x ^ 2-13x-15 x 5

9.) Division of the synthesis and use the remainder theorem to find that P (a).
P (x) = x ^ 4 +3 x ^ 3-6x ^ 2-10x 8, a = 2
