WebFeb 10, 2024 · A quadratic equation is a polynomial equation in a single variable where the highest exponent of the variable is 2. [1] There are three main ways to solve quadratic equations: 1) to factor the quadratic equation if you can do so, 2) to use the quadratic formula, or 3) to complete the square. WebNov 16, 2024 · Section 5.2 : Zeroes/Roots of Polynomials. 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.
