What it does
Applies the quadratic formula or factoring path to find roots.
How to use it
Enter coefficients a, b, c, then solve.
Formula
x = (−b ± √(b² − 4ac)) / (2a).
Example
x² − 5x + 6 = 0 → roots 2 and 3.
FAQs
What if a = 0?
That is not quadratic; the tool should treat it as linear or invalid.
Complex roots?
When discriminant < 0, roots are complex conjugates.
Factoring vs formula?
Both agree; the formula always works when a ≠ 0.
