Polynomial Equation Solver
Free online polynomial equation solver. Solve polynomial equations of any degree with real and complex roots. Find solutions for linear, quadratic, cubic, and higher-degree polynomials.
A polynomial equation solver that finds all real and complex roots of polynomial equations of any degree.
What is a Polynomial Equation?
A polynomial equation is an equation of the form:
anxn + an-1xn-1 + ... + a1x + a0 = 0
where n is a non-negative integer (the degree), and a₀, a₁, ..., aₙ are coefficients with aₙ ≠ 0.
How Does the Polynomial Solver Work?
This calculator uses numerical methods to find polynomial roots:
- For degree 1: Direct solution using linear equation formula
- For degree 2: Quadratic formula for exact solutions
- For degree 3: Cubic formula or numerical approximation
- For degree 4+: Numerical root-finding algorithms (Newton-Raphson method)
