We construct square matrices whose determinant is exactly the resultant. The matrices constructed are of hybrid Sylvester and Bézout type. We make use of the exterior algebra techniques of Eisenbud, Fløystad, and Schreyer.18 pages, 2 figuresAlgebraic GeometryCommutative AlgebraCombinatorics14Q99; 13P99text
