Solve any quadratic equation: ax² + bx + c = 0 — with step-by-step solution
Enter the coefficients a, b, and c. Fractional values (e.g., 3/4) are accepted. a cannot be zero.
x = [-b ± √(b² - 4ac)] / (2a)
The ± means two solutions: one with +, one with -.
Δ = b² - 4ac
• Δ > 0: Two real roots
• Δ = 0: One real root (repeated)
• Δ < 0: Two complex roots
