I am stuck on a problem concerning second derivatives and was wondering if you could provide

some help.

orignial function:

f(x)= (e^x)/x

I believe i figured out the first derivative using the quotient rule.

f'(x)= [e^x(x-1)] / x^2

Now, I am not sure what to do with the top. I know the chain rule is

somewhere in there. Any advice would be great, thank you.
