... classification or solution. In the case of a quadratic equation ax 2 + bx + c = 0, the discriminant is b 2 − 4ac; for a cubic equation x 3 + ax 2 + bx + c = 0, the discriminant is a 2b 2 + 18abc − 4b 3 − 4a 3c − 27c. The discriminant of an equation gives an idea of the number of roots and the nature ...
