I have the following differential equation:
r^2f''(r)+2rf'(r)-2f(r)=0
I think a solution has something to do with Bessel functions but I can't figure out how. Could somebody help me to find a solution?
Thanks!

This is a Cauchy-Euler equation. I think this Wikipedia page explains quite well how to attack it.
