Separation of Variables

Hello,
My problem is using separation of variables for what is equivalent to a PDE. The problem is of the form

dT [color=white]```[/color] d^2T
--- = A ------- +B
dt [color=white]```[/color] dy^2

The examples I've found all are only of first order, and don't have a constant added on. Using the assumption of T(t,y)=X(t)+Y(y) seems to be about what I need, but then I'm not sure what to do about B.

Thanks,
-Z

Start with T=S+Bt. The equation in S will not have B in it.
