## Homework Statement

Normalise ψ=Ae^(-λχ)e^(-iδt)

## Homework Equations

I know you have to intergrate ψ^2 i.e (ψxψ*)

## The Attempt at a Solution

Im literally just stuck at the first bit , i can do the rest. I have the solutions manual and I dont understand how they get 2|A|^2 e^(-2λχ) from ψxψ*well only the 2 in front of A^2 really when i do it i get |A|^2 e^(-2λχ)

thanks for the help
