Quadratic Formula ax² + bx + c = 0

Enter coefficients to solve quadratic equations step by step.

1x² + -3x + 2 = 0

a =

b =

c =

Solutions (roots)

x = 2, x = 1

Discriminant (Δ) 1

Step 1: Calculate discriminant

Δ = b² - 4ac = (-3)² - 4(1)(2) = 9 - 8 = 1

Step 2: Apply quadratic formula

x = [3 ± √1] / 2 = [3 ± 1] / 2

Step 3: Find roots

x₁ = (3 + 1)/2 = 2, x₂ = (3 - 1)/2 = 1
