摘要
介绍了一元三次方程一般式化为标准式的方法,结合图形给出了标准式的实数根的分布情况,从而解决了任意一元三次方程的实数根的分布的问题。
The method that simple cubic equation was changed from general to standard was introduced and the distribution of standardized real root was illustrated, which solved the problem of the distribution of any real root for simple cubic equation.
