Quadratic Formula Calculator
Solve ax² + bx + c = 0 for real or complex roots.
Assumptions used in this calculation
- Complex roots: When the discriminant is negative, roots are reported in a + bi complex form rather than being treated as no solution.
About this calculator
The quadratic formula calculator solves ax² + bx + c = 0, returning two real roots, one repeated root, or complex roots depending on the discriminant.
Worked example
x² − 5x + 6 = 0
Result: x₁ = 3, x₂ = 2
