This paper presents a simplified method of expressing the solution to cubicequations in terms of function evaluation only. The method eliminates the needto manipulate the original coefficients of the cubic polynomial and makes thesolution free from such coefficients. In addition, the usual substitutionneeded to reduce the cubic equation is implicit in that the final solution isexpressed in terms only of the function and derivative values of the givencubic polynomial at a single point. The proposed methodology simplifies thesolution to cubic equations making them easy to remember and solve.
