Question

Use the Product Rule to find the derivative of the function.

f(x) = (x^3 − 2x)(5x^2 + 2x)

Answer 1

The Product Rule is:

(First*Derivative of Second)+(Second*Derivative of First)
In your case: First is (x^3-2x) and Second is (5x^2+2x)
Try that and write back if you're still having trouble.
