WebCardano's method provides a technique for solving the general cubic equation. ax 3 + bx 2 + cx + d = 0. in terms of radicals. As with the quadratic equation, it involves a "discriminant" whose sign determines the number (1, 2, or 3) of real solutions. However, its implementation requires substantially more technique than does the quadratic formula.
