**1. Homework Statement**

potential V(x)=-αδ(x+a)-αδ(x-a)

write down the general normalizable solution to the time independent Schrodinger equation in the case E<0, without yet imposing any boundary conditions.

**2. Homework Equations**

**3. The Attempt at a Solution**

I divided this problem into three regions x<=-a, x>=a and -a<x<a, then I got general solutions for each region, then added all those gen. solutions and got:

Ψ(x)=Aexp(Kx)+Bexp(-Kx)+[Cexp(Kx)+Dexp(-Kx)]

K=(-2mE/h)^1/2

I don't think this is right though....

can you help me out?
