Take the derivative of that
Now just simplify

You can use the quotient rule, but I don't quite remember it, so I'll just give you the necessary information.
Top = x
Derivative of the top= 1
Bottom = (x + c/x)
Derivative of the bottom = 1 + -c/(x^2)
Assuming that c is a constant.
i'm not sure if c is a constant but the answer is f'(x)=2cx/(x^2+c)^2
