assumptions of polynomial coefficients being zero outside the indices [0,J] and [0,K] for f(x) and g(x) respectively, there is nothing wrong in writing this formula as: We can now form the (finite) sequences f[n], g[n], h[n] for the coefficients of the polynomials f(x), g(x) and h(x) and define the
