Proving the dor product of 4-vectors is Lorentz invariant

1. The problem statement, all variables and given/known data
Let A and B be 4-vectors. Show that the dot product of A and B is Lorentz invariant.

3. The attempt at a solution
Should I be trying to show that [itex]A.B=\gamma(A.B)[/itex]?

Thanks
