关于四次方程已知有多种解法,如文[1]、[2].本文将给出另一种解法,这一解法仍然基于将四次方程化为三次方程求解,但步骤要简单些,不要先将一般四次方程化为缺三次项的四次方程,然后再化为一般三次方程,再又将一般三次方程化为缺二次项的三次方程求解.本文一次性将一般四次方程化为缺二次项的三次方程求解,其中省去了两个步骤. There are many known solutions to the quadratic equations, such as [1], [2]. This paper presents another solution that is still based on solving a quadratic equation into a cubic equation, but the steps are simpler , Do not first general four equations into the lack of cubic terms of the four equations, and then re-generalized cubic equation, and then the general cubic equation into the lack of quadratic cubic equations.This article will be a general four times The equation is solved as a cubic equation without quadratic terms, eliminating two steps.
