What is a quadratic equation?

A quadratic equation is of the form ax² + bx + c = 0, where a ≠ 0. It can have 0, 1, or 2 real solutions.

What is the discriminant?

The discriminant (b² − 4ac) determines the nature of roots. Positive = 2 real roots, zero = 1 repeated root, negative = no real roots.

Can it solve higher-degree equations?

Currently, the solver handles linear (degree 1) and quadratic (degree 2) equations. Higher degrees will be added in the future.
