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. … WebNov 16, 2024 · We’ll start off this section by defining just what a root or zero of a polynomial is. We say that x = r x = r is a root or zero of a polynomial, P (x) P ( x), if P (r) = 0 P ( r) = 0. In other words, x =r x = r is a root or zero of a polynomial if it is a solution to the equation P (x) = 0 P ( x) = 0. WebRecipe: A 2 × 2 matrix with a complex eigenvalue.
