WebMar 4, 2024 · Zeros of a polynomial are the values of $x$ for which the polynomial equals zero.In other words, they are the solutions of the equation formed by setting the polynomial equal to zero. The zeros of a polynomial can be real or complex numbers, and they play an essential role in understanding the behavior and properties of the polynomial function. WebA polynomial of degree n has n solutions. So let's look at this in two ways, when n is even and when n is odd. 1. n=2k for some integer k. This means that the number of roots of the polynomial is even. Since the graph of the polynomial necessarily intersects the x axis an even number of times. If the graph intercepts the axis but doesn't change ... lines from a hat
