im trying to prove the galileo invariance of s.e. But i get stuck with an extra term prop.to v*d/dx
in fact i get invariance only for scaling x' equ. ax and t' equ. at.
Where does the mistake hide ?

Can't do it, it isn't invariant with respect to Galilean transformations.

Try to change the wavefunction as well: multiply it by a space-time dependent phase factor.
