Polynomial Root Finder & Factorization Calculator

Find the roots (zeros) of a polynomial equation P(x) = anxn + ... + a1x + a0 = 0. Enter the coefficients to find all real and complex roots.

(Maximum degree supported is typically limited by the solver library)
x3 +x2 +x + = 0
Enter coefficients from highest degree (an) down to the constant term (a0).

About the Polynomial Root Finder

This calculator finds the roots (zeros) of a polynomial equation P(x) = 0 by using its coefficients. It identifies both real and complex roots.

Useful for solving equations and analyzing functions in algebra and engineering. You might also need the Equation Solver Calculator or Complex Number Calculator.
