Formula
x = (−b ± √(b² − 4ac)) / 2a
Discriminant b² − 4ac determines zero, one, or two real roots.
Example
- Discriminant: 25 − 24 = 1
- Roots: (5 ± 1)/2= x = 3, 2
Result: Solutions: x = 3 and x = 2
Frequently Asked Questions
a = 0?
Not quadratic—reduces to linear equation.
Complex roots?
Negative discriminant yields imaginary components.
Factoring?
Integer roots may factor; formula always works.
