Quadratic Formula

The Formula

x = (-b ± √(b² – 4ac)) / 2a. This formula gives the solutions (roots) of any quadratic equation ax² + bx + c = 0.

Discriminant (b² – 4ac)

If positive: two distinct real roots. If zero: one repeated real root. If negative: two complex conjugate roots.

Vertex Form

The vertex of the parabola is at x = -b/2a. The y-coordinate is found by substituting this x value back into the equation.
