在学习了《整式》这一章的内容后,同学们经常会遇到整式运算中的求值问题,解这类题目时一般要用到以下的方法与技巧.1直接代入求值把已知条件中所给字母的值,直接代入所求式子里计算求值,这是最基本的方法.例1已知m=-121,求整式4m3-89m2+3m+2030的值.解因为m=-121,所以原式=4[- After learning the content of the chapter “Integrative”, students often encounter the problem of evaluation in integer arithmetic. The following methods and techniques are generally used when solving such problems: Conditions given in the letter value, directly into the calculation formula for calculating the value, which is the most basic method.Example 1 Known m = -121, find the value of the integral 4m3-89m2 +3 m +2030 solution because m = -121, so the original = 4 [-
