About the Quadratic Formula Calculator
The quadratic formula solves any equation of the form ax² + bx + c = 0 for x, where a ≠ 0.
Formula: x = (−b ± √(b² − 4ac)) ÷ 2a
The discriminant (b² − 4ac) tells you the nature of the roots: positive gives two real roots, zero gives one repeated root, and negative gives two complex roots.
