WebNov 2, 2024 · So, for any cubic equation in the form of: a x 3 + b x 2 + c x + d = 0 Our vertex point is − b 3 a if there are 3 real roots, and − b a if there is 1 real root, as the sum of real roots of a cubic equation is equal to − b a. The discriminant of a quadratic equation is obtained by replacing x with the vertex point, − b 2 a.
