Free Quadratic Equation Solver (Real & Complex Roots with Steps) Online
Solve any quadratic equation ax² + bx + c = 0 instantly. Computes discriminant (b² - 4ac), real roots, and complex imaginary roots with full steps. — 100% free online utility, zero sign-up, zero paywalls, and private client-side processing.
How It Works
Enter Coefficient a
Input quadratic coefficient (a ≠ 0).
Enter Coefficients b & c
Input linear coefficient b and constant term c.
Review Discriminant
Inspect Δ = b² - 4ac to determine root nature (two real, one real, or two complex).
Copy Solved Roots
Copy exact radical and decimal root solutions.
