Method (no overloads)
Summary
The resultant of two polynomials with respect to mainVariable ,
itself a polynomial in the remaining variables; null where a step declines.
itself a polynomial in the remaining variables; null where a step declines.
Remarks
Identically zero exactly when the two share a factor of positive degree in
mainVariable . Where it is not identically zero it vanishes at
a point of the remaining variables exactly where the two polynomials specialised
there have a common root, or where both of their leading coefficients in
mainVariable vanish — the second is why an eliminant can carry
a root the original system does not have.
