Perturbation Theory: Solving a/r+br Potential

[Korova]

A quick question from a high school student,

In perturbation theory, what is to be done with the found energy correction? I'm working out the solution to an a/r+br potential and using br as the perturbation. I set up the integral and normalized, but what do I do with the expression that I'm getting?

Thanks in advance,
Korova

bleh... nevermind... I figured it out.
