本文以初中数学竞赛试题为例,谈谈配方法的应用,供参考.一、求值例1(第11届希望杯)设a2-b2=1+2,b2-c2=1-2,则a4+b4+c4-a2b2-b2c2
This article takes the junior middle school math contest as an example to talk about the application of matching methods for reference. First, evaluation example 1 (the 11th hope cup) set a2-b2=1+2, b2-c2=1-2, then A4+b4+c4-a2b2-b2c2
