Quadratic Formula Calculator

Solve quadratic equations of the form ax² + bx + c = 0 using the quadratic formula, with step-by-step solutions.

1x² - 5x + 6 = 0

Root x₂
2

Step-by-Step

Equation: 1x² + -5x + 6 = 0

Discriminant: Δ = b² - 4ac = -5² - 4(1)(6) = 1

Δ > 0 — two real roots

x = (-b ± √Δ) / (2a)

x₁ = (--5 + √1) / (2 × 1) = 3

x₂ = (--5 - √1) / (2 × 1) = 2

Quadratic Formula

x = (-b ± √(b² - 4ac)) / (2a)
