Quadratic Formula
The solutions to any quadratic equation can be found using the quadratic formula:
x = [-b ± √(b² - 4ac)] / 2a
Discriminant
The discriminant (D = b² - 4ac) determines the nature of the roots:
- D > 0: Two distinct real roots
- D = 0: One real root (repeated)
- D < 0: Two complex roots
Examples
Example 1: x² - 3x + 2 = 0
Solutions: x = 1, x = 2
Example 2: x² + 4x + 4 = 0
Solution: x = -2 (double root)
Example 3: x² + x + 1 = 0
Solutions: Complex roots
