Example Usage
Example 1: x² + 5x + 6
- Discriminant: 25 – 24 = 1
- Roots: x = -2, x = -3
- Factored Form:
(x + 2)(x + 3) - Verification:
(x + 2)(x + 3)→x² + 5x + 6✅
Example 2: 2x² + 7x + 3
- Discriminant: 49 – 24 = 25
- Roots: x = -3, x = -0.5
- Factored Form:
2(x + 3)(x + 0.5) - Verification: Expand →
2x² + 7x + 3✅
