Best ResponseYou've already chosen the best response.1If a polynomial has a zero at k, then x  k is a factor of the polynomial. In your case, the polynomial has a zero at 5, so x  5 is a factor. It has a zero at 4, so x  (4) is also a factor. This factor is simply x + 4. Now do the same for the zero at 1 and find its factor. Then multiply the three factors together and collect like terms and that is the polynomial.
