Question

Find the derivative of the following:
f(x)= (8x +3)(2x^2 -x -1)

Is it easier to begin with the product rule or the power rule? How is it best to determine which rule to use?

Answer 1

I would multiply through then use power rule to find your answer. So (8x + 3)(2x^2 -x -1) = 16x^3 - 8x^2 - 8x + 6x^2 - 3x -3. Simplify then use power rule

Answer 2

So the final answer would be 48x^2-4x-11?

Answer 3

yes

Answer 4

Awesome thanks:)
