[tex]\psi(x) = e^{-\kappa|x|} + A e^{-Bx} + C e^{-Dx} [/tex]

where A, B, C and D are constants you will have to determine, and you will likely have to stitch together two different solutions at the origin using the continuity arguments you are already familiar with.

The author of this problem had no intention on turning it into a bad PhD thesis, LOL. For more information on solving inhomogeneous differential equations, see, for example:
