How to solve zeros of polynomial functions

WebJul 13, 2024 · When finding the zeros of polynomials, at some point you’re faced with the problem x2 = − 1. While there are clearly no real numbers that are solutions to this equation, leaving things there has a certain feel of incompleteness. To address that, we will need utilize the imaginary unit, i. Definition: Imaginary number i WebMethod: finding a polynomial's zeros using the rational root theorem Step 1: use the rational root theorem to list all of the polynomial's potential zeros. Step 2: use "trial and error" to find out if any of the rational numbers, listed in step 1, are indeed zero of the polynomial.
