In algebra, the factor theorem is a theorem linking factors and zeros of a polynomial. It is a special case of the polynomial remainder theorem. The factor theorem states that a polynomial has a factor if and only if (i.e. is a root). More generally, a bivariate polynomial has a factor if and only is the zero polynomial. The above theorem is the case where
