Steady-state concentration for particles diffusing in potential U(x) = ax²

[superwolf]

N particles diffuse in one dimension in the potential U(x) = ax^2, with a > 0.
Find steady-state concentration, c0(x).

No idea how to solve this. Any equations?

Here's the answer

I still don't understand HOW they obtain that expression...
