What is the Polynomial Roots Calculator?
Enter the coefficients from the highest power down (for example 1, -6, 11, -6 means x³ - 6x² + 11x - 6) and get every root, including complex ones. It uses the Durand–Kerner method, which finds all roots of a polynomial at the same time.
How to use the Polynomial Roots Calculator
- Type coefficients separated by commas or spaces, highest power first.
- Use 0 for missing terms.
- Read the roots and the factored form.
How many roots will I get?
A polynomial of degree n always has n roots (counting complex and repeated ones).
This Polynomial Roots Calculator is 100% free, needs no signup and runs privately in your browser – on phone, tablet or computer.
