Quadratic Equation Solver

Solve ax² + bx + c = 0 — real roots, complex roots, linear case — nothing is uploaded.


Quadratic equation solver

Enter coefficients a, b, c for the equation ax² + bx + c = 0. The discriminant Δ = b² − 4ac determines the result: Δ > 0 gives two real roots; Δ = 0 gives a double root; Δ < 0 gives complex conjugate roots.

If a = 0 the solver falls back to the linear equation bx + c = 0.

FAQ

What are complex roots? When the discriminant is negative, roots include an imaginary part √(−Δ) / (2a).
