Resultant

Resultant[poly1, poly2, var]
computes the resultant of the polynomials poly1 and poly2 with respect to the variable var.
Resultant[poly1, poly2, var, Modulus->p]
computes the resultant modulo the prime p.
  • The resultant of two polynomials p and q, both with leading coefficient one, is the product of all the differences pi-qj between roots of the polynomials. The resultant is always a number or a polynomial.
