Homework Help: Quick derivation question Quantum Mechanics

  1. Feb 1, 2015 #1
    1. The problem statement, all variables and given/known data
    Having one of those days where nothing makes sense, here is the derivation:


    how does he get the two circled terms from what he's derived above?

    2. Relevant equations

    3. The attempt at a solution
    I tried substitution but get nowhere I just cant see how the early expressions help in getting the circled expressions.

    once again, any pointers in the right direction would be appreciated
