We consider the hp-version to solve non-constant coefficients elliptic equations with Dirichlet boundary conditions on a bounded, convex polygonal domain Ω in R^2. In this paper we consider a family G_p = {I_m} of numerical quadrature rules satisfying certain properties, which can be used for calculating the integrals. When the numberical quadrature rules I_m ∈ G_p are used for calculating the integrals in the stiffness matrix of the variational form we will give its variational form and derive an error estimate of ||u-??||_1Ω.
