The Quadratic Formula
For a quadratic equation ax² + bx + c = 0, the values of x (the roots) can be found using:
x = [-b ± √(b² - 4ac)] / 2a
The Discriminant
The term inside the square root, b² - 4ac, is called the discriminant.
- positive: Two real solutions.
- zero: One real solution.
- negative: Two complex (imaginary) solutions.
