Step-by-Step Worked Example

Scenario: Solve x² - 5x + 6 = 0

1. Identify coefficients: a = 1, b = -5, c = 6
2. Calculate discriminant: Δ = (-5)² - 4(1)(6) = 25 - 24 = 1
3. Apply quadratic formula: x = (5 ± √1) / 2 = (5 ± 1) / 2
4. Roots: x₁ = 3.0, x₂ = 2.0
5. Parabola vertex: (2.5, -0.25)
Final Calculated Result: x₁ = 3, x₂ = 2 (Vertex at 2.5, -0.25)
