Solve ax² + bx + c = 0. Enter coefficients a, b, c to find the roots.
Quadratic formula
x = (-b ± √(b² - 4ac)) / (2a)
Understanding the quadratic formula
The quadratic formula solves any equation of the form ax² + bx + c = 0. The discriminant D = b² - 4ac determines the nature of the roots: if D > 0, two distinct real roots; if D = 0, one repeated root; if D < 0, two complex conjugate roots. This calculator handles all cases.
