Quadratic Equation Solver
MathSolve ax² + bx + c = 0 and find roots.
Solves ax² + bx + c = 0
A quadratic equation has the form ax² + bx + c = 0. Its roots are found with the quadratic formula x = (−b ± √(b²−4ac)) ÷ 2a, where the discriminant (b²−4ac) determines the nature of the solutions: positive discriminant gives two distinct real roots, zero gives one repeated root, and negative gives two complex conjugate roots. This solver handles all three cases automatically.
