Polynomial algebra offers a standard approach to handle several problems ingeometric modeling. A key tool is the discriminant of a univariate polynomial,or of a well-constrained system of polynomial equations, which expresses theexistence of a multiple root. We concentrate on bivariate polynomials andestablish an original formula that relates the mixed discriminant of twobivariate Laurent polynomials with fixed support, with the sparse resultant ofthese polynomials and their toric Jacobian. This allows us to obtain a newproof for the bidegree of the mixed discriminant as well as to establishmultipicativity formulas arising when one polynomial can be factored.
