Quadratic Equation Solver - ax² + bx + c = 0 (Real & Complex Roots)
Solve any quadratic ax² + bx + c = 0 - real or complex roots, discriminant, and vertex
使い方
- 1Enter a, b, c
The three coefficients of ax² + bx + c = 0. Any real numbers, positive or negative.
- 2Read the roots
Two real, one repeated, or two complex conjugate roots depending on the discriminant.
- 3See vertex and discriminant
Vertex tells you the parabola's minimum or maximum point. Discriminant (b²−4ac) sign classifies the roots.

よくある質問
What is the quadratic formula?
x = (−b ± √(b²−4ac)) ÷ 2a. The ± gives two solutions when the discriminant is positive.
What happens if a = 0?
The equation is linear, not quadratic. The tool solves x = −c ÷ b when b is non-zero.
What are complex roots?
When b² − 4ac < 0 the square root is imaginary, giving two complex conjugate solutions of the form p ± qi.
