  We use the Brans-Dicke theory from the framework of General Relativity
(Einstein frame), but now the total energy momentum tensor fulfills the
following condition $\rm[\frac{1}{\phi}(8\pi T^{\mu \nu (M)}+T^{\mu\nu
(\phi)})]_{;\nu}=0$. We take as a first model the flat FRW metric in the
Hamilton-Jacobi scheme and we present the Lagrange-Charpit approach in order to
find classical solutions. In the quantum scheme, once we determine the
characteristic surfaces, the quantum solution is obtained. These two classes of
solutions are found for all values of the barotropic parameter $\gamma$.
