Quadratic formula solver
Solve any equation of the form ax² + bx + c = 0 using the quadratic formula. Enter the three coefficients and the solver returns the roots — two real roots, one repeated root, or a pair of complex roots — depending on the discriminant (b² − 4ac).
The formula x = (−b ± √(b² − 4ac)) / 2a is applied entirely in your browser, so the coefficients you enter are never uploaded.
