# Thread: I need help with this derivative question: find f'(x) for f(x)=x^2 lnx - x^2

1. ## I need help with this derivative question: find f'(x) for f(x)=x^2 lnx - x^2

I am completely stuck on this problem and I don't know where to go from here! Can someone guide me in the right direction?

Find the indicated expressions for the given function: f(x)=x2lnx-x2

a. f '(x) I'm pretty sure I've figured this part out...

b. f '(e) This is the one I am completely lost on

What did you get for f'(x)?

Did you not take algebra before taking calculus? Because all part (b) is asking you to do is evaluate the derivative function at the given value. Please let us know if you're needing lesson instruction on evaluating functions. Thank you!
