How to find the roots of a polynomial equation. Nov 6, 2024 · To solve a polynomial equation, we find the values of x that satisfy the equation. The calculator computes exact solutions for quadratic, cubic, and quartic equations. Polynomials of degree 5 or higher have no simple formula that always works. So what do we do with ones we can't solve? Try to solve them a piece at a time! Polynomial roots calculator This free math tool finds the roots (zeros) of a given polynomial. The roots of a polynomial equation may be found exactly in the Wolfram Language using Roots [lhs==rhs, var], or numerically using NRoots [lhs==rhs, var]. These solutions, known as the roots of the polynomial, are found by setting the equation equal to zero and solving for the variable. Oct 4, 2025 · To factor a polynomial function f and find its real roots: Step 1: Find a root c by inspection (look at the polynomial and making an educated guess at a number easy to plug in, like ± 1 or ± 2, or use the Rational Root Theorem, and test options). .
