Question

how do i do this?

Answer 1

What have you tried? What are you struggling with?

Answer 2

for the first derivative, after using the product rule, i'm getting 2e^-x + 2xe^-x

after that, when i try to find the second derivative i end up doing the product rule again but i get another term plus at the end the same term as the original y. How would i go about finding the second derivative?
