Common Questions
What formula does the Quadratic Formula Calculator use?
x = (-b +/- sqrt(b^2 - 4ac)) / (2a) = 0, where b^2 - 4ac is the discriminant.
What does the discriminant tell me?
The discriminant b? - 4ac shows whether the equation has two real roots, one repeated real root, or complex roots.
