[知识精要]1.认识配方法初中数学上的配方法,是指将代数式通过凑配等手段,得到完全平方式,再利用诸如完全平方项是非负数这一性质解题.同一个式子可以有不同的配方结果,可以配一个平方式,也可以配多个平方式;配方的对象也具有多样性,数、字母、式、函数关系等都可以进行配方.配方法是中学数学的一种重要的思想方法,它广泛应用于初中数学的各个方面,诸如代数式的化简求值、计算、解方程(组)、解不等式、求最值、证明等式等方面.
[Knowledge Essentials] 1. Cognitive matching method The mathematics matching method in junior middle school means that the algebraic equations are completely flat by means of fitting, etc., and the problem is solved by the use of a property such as a complete square term which is non-negative. Can have different formula results, can be equipped with a flat mode, can also be equipped with multiple flat mode; the formula’s objects also have diversity, numbers, letters, formulas, function relations, etc. can be formulated. With the method is a middle school mathematics An important way of thinking, it is widely used in all aspects of junior high school mathematics, such as algebraic reductions, calculations, solving equations (groups), solving inequalities, seeking the most value, and proof of equality.
