Apply the definition of a Hermitian operator on the inner product (which is an integral), do a partial integration and use that wave functions have to be in L2 (and thus have certain boundary conditions at infinity).

Whether the momentum operator for a particle in 1D is selfadjoint or not is a matter of boundary conditions. See the discussion from pages 13 from http://www.hep.caltech.edu/~fcp/math.../linDiffEq.pdf
