Quadratic Equations — Key Formulas
| Formula | Expression |
|---|---|
| Quadratic formula | x = (-b ± √(b² - 4ac)) / 2a |
| Discriminant (Δ) | Δ = b² - 4ac; Δ > 0: 2 roots; Δ = 0: 1 root; Δ < 0: no real roots |
| Nature of roots | Δ = perfect square → rational; Δ < 0 → imaginary |
| Sum of roots (α + β) | α + β = -b/a |
| Product of roots (αβ) | αβ = c/a |
| Quadratic with given roots | x² - (α+β)x + αβ = 0 |
| Completing the square | ax² + bx + c = a(x + b/2a)² - (b²/4a) + c |
