Subresultants

Subresultants[poly1, poly2, var] generates a list of the principal subresultant coefficients of the polynomials poly1 and poly2 with respect to the variable var.

• Subresultants[poly1, poly2, var, Modulus -> p] computes the principal subresultant coefficients modulo the prime p.

Examples

Subresultants[x^3 + 2 x + 1, x^2 - 1, x]
