Theorem ply1rem

Description: The polynomial remainder theorem, or little Bézout's theorem (by contrast to the regular Bézout's theorem bezout ). If a polynomial F is divided by the linear factor x - A , the remainder is equal to F ( A ) , the evaluation of the polynomial at A (interpreted as a constant polynomial).
