 Homework Statement:

The problem states work for word.
Using canonical quantization relation, prove that
sum operator ((E_n E_0)) < E_n  X  E_0 >^2) = constant
Where E_0 is the energy corresponding to the eigenstate  E_0 >. Determine the value of the constant. Assume the hamiltonian had a general form H = P/2m +V(X)
Hint: One way to proof this is to think how [H, X], X] is connected to the obove identity.
 Relevant Equations:
 all equations i have are in the statement.
I have no idea where to start with this problem. I am interested in any hints, or ways to proof this. But i would especially like to know how the commutator is connected to the identity.
