This paper is devoted to quadrature formulas which multiple nodes. First, some properties of power-orthogonal polynomials are presented. Then generalized Gaussian quadrature formulas with multiple nodes, including stable algorithms for numerical construction of the corresponding polynomials and Cotes numbers, are given. Finally, some applications to moment-preserving spline approximation are presented.
