不可约多项式的一个应用

An application of irreducible polynomials

从一个有名的问题及其几种解法入手,通过把这个问题进行一般化来检验这些解法的适用范围,由此说明在解题时,理解基本概念是非常必要的,运用基本概念进行推理有助于理解问题的本质.

Starting with a well-known problem and its several solutions,the application circumstances of these solutions are tested by generalizing this problem,which show that when solving problems,it is necessary to understand the basic concept,and it is helpful to use the basic concepts for reasoning to understand the nature of the problem.
