The critical points of a cubic equation are those values of x where the slope of the cubic function is zero. They are found by setting derivative of the cubic equation equal to zero obtaining: f â²(x) = 3 ax 2 + 2 bx + c = 0.n other words, a cubic function is defined by a polynomial of degree three. Setting Æ (x) = 0 produces a cubic equation of the form: Usually, the coefficients a, b, c, d are real numbers. However much of the theory of cubic equations for real coefficients applies to other types of coefficients (such as complex ones).
