Polynomial Roots Calculator
Enter coefficients for a polynomial up to degree four to compute all real and complex roots.
Mathematical tool for education; verify results for critical applications.
Examples
- x² - 5 = 0 ⇒ 2.2361, -2.2361
- x⁴ + 1 = 0 ⇒ 0.7071+0.7071i, -0.7071+0.7071i, -0.7071-0.7071i, 0.7071-0.7071i
FAQ
What if the leading coefficient is zero?
The calculator automatically reduces the polynomial degree.
Are complex roots included?
Yes, complex roots are shown with an i to denote the imaginary part.
How precise are the results?
Roots are approximated to four decimal places.
Additional Information
- Handles polynomials from linear up to quartic degree.
- Outputs roots separated by commas; complex numbers include the i suffix.
