So I'll write out, step by step, what I've done:
Right Hand Side:
Left Hand Side:
Rewriting LHS using partial fractions:
So then I get LHS to be:
Integrating the LHS with respect to y gives
So now I have
But apparently that's the wrong answer and I can't, for the life of me, figure out where I'm going wrong.
