所谓赋值,就是给命题中某些字母(或量)赋上一定的数值,然后化为“数字”问题考虑。这样做,常可以简化某些证明过程,收到以简驭繁、化难为易的效果。一、给字母赋值分解因式大家熟知的多项式的因式分解,是一种带有较强技巧性的数学问题,特别是对于一些次数较高或元数较多的多项式因式分解,解法更显得困难。下面介绍 The so-called assignment is to assign certain numbers (or quantities) to the propositions with certain values ​​and then consider them as “numbers”. In doing so, it is often possible to simplify certain certification processes and receive results that are simple and complicated and difficult to achieve. 1. The factorization of the polynomials that are well-known for letter assignment is a mathematics problem with strong skills, especially for polynomial factorization with higher or higher arity. It is difficult. The following is introduced
