In this paper, we develop two variants of Bezout subresultants for several polynomials, i.e., hybrid Bezout subresultant and non-homogeneous Bezout subresultant. They are the extensions of the variants of Bezout subresultants for two polynomials to arbitrary number of polynomials. Experimental results show that the Bezout-type subresultants behave better than other known formulas when used to compute multi-polynomial subresultants, among which the non-homogeneous Bezout formula shows the best performance.
