Thread: Derivatives involving both product/quotient rule

Find f'(x) for y = (x+5 / x+1) (2x+1)

I don't know how to proceed here. Do I use the quotient rule inside the first brackets? Then what?

First thing you can do is use the product rule
.
From here we can take the derivative using the quotient rule on .
Combine this with the previous result
.
Now simplify.

You don't end up with do you?

Yes, that is what www.wolframalpha.com gives.
