did i get the right answer?

Use the product rule to find the derivative.

f(x) = (x^2 - 2x + 2)(4x^3 - x^2 + 4)

a. f'(x) = 4x^4 - 32x^3 + 30x^2 + 4x - 8
b. f'(x) = 4x^4 - 36x^3 + 30x^2 + 4x - 8
c. f'(x) = 20x^4 - 36x^3 + 30x^2 + 4x - 8
d. f'(x) = 20x^4 - 32x^3 + 30x^2 + 4x - 8

That's nice. How did you decide on that one?
