WebJul 12, 2024 · If p(x) is a polynomial of degree 1 or greater and c is a real number, then when p (x) is divided by x − c, the remainder is p(c). If x − c is a factor of the polynomial p, then p(x) = (x − c)q(x) for some polynomial q. Then p(c) = (c − c)q(c) = 0, showing c is a zero of the polynomial. WebFinding the zeros of a polynomial function (recall that a zero of a function f ( x) is the solution to the equation f ( x) = 0) can be significantly more complex than finding the zeros of a linear function.
