Integrate a sum of functions

please help me integrate : ( (f(x) * f"(x) - f'(x))^2 ) / f^2(x) dx
Does the above mean the below?

. . . . .\(\displaystyle \displaystyle \int\, \dfrac{\left(f(x)\, \cdot\, f"(x)\, -\, f'(x)\right)^2}{f^2(x)}\, dx\)

Also, are you given any information regarding the function and its derivatives?

When you reply, please include a clear listing of all of your efforts so far, even if you think they're wrong, so we can see what's going on. Thank you! ;)
