[tex]\int[/tex] ([tex]\hat{p}[/tex][tex]\Psi[/tex]1)*[tex]\Psi[/tex]2 + i [tex]\int[/tex] ([tex]\hat{x}[/tex][tex]\Psi[/tex]1)[tex]\Psi[/tex]2

to

[tex]\int[/tex] ( ([tex]\hat{p}[/tex]-i[tex]\hat{x}[/tex]) [tex]\Psi[/tex]1)*[tex]\Psi[/tex]2

using the fact that p and x are Hermitian.

im sure its painfully simple but i cant see it.
