I was doing this problem from Griffith's electrodynamics book and can't figure out how to do this integral. The author suggested partial fractions but the denominator has a fractional exponent which I have never seen for partial fractions, and so, I am unsure how to proceed. The integral I am working on is this:

$$\int \frac{Z-Ru}{(R^2-z^2-2RZu)^{3/2}}du$$

Where u is the variable of integration and all the other ones are constants.

No idea how to get started, please give a hint.
