WebFirst, find the real roots. And let's sort of remind ourselves what roots are. So root is the same thing as a zero, and they're the x-values that make the polynomial equal to zero. So the real roots are the x-values where p of x is equal to zero. My graphing software also shows x=5 and x=-5 as my x-intercepts on the graph of … 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.
