论文摘要
本文提出了一种仅根据功能评估来表达对立方方程的解决方案的简化方法。该方法消除了操纵立方多项式的原始系数的需求，并使溶液不受此类系数。此外，减少立方方程所需的通常替代是隐含的，因为最终解决方案仅以单个点的给定立方多项式的函数和衍生值表示。提出的方法简化了对立方方程的解决方案，使其易于记住和解决。
This paper presents a simplified method of expressing the solution to cubic equations in terms of function evaluation only. The method eliminates the need to manipulate the original coefficients of the cubic polynomial and makes the solution free from such coefficients. In addition, the usual substitution needed to reduce the cubic equation is implicit in that the final solution is expressed in terms only of the function and derivative values of the given cubic polynomial at a single point. The proposed methodology simplifies the solution to cubic equations making them easy to remember and solve.
