配方法 ,在数学上是指将代数式通过凑配等手段 ,得到完全平方形式 ,再利用诸如完全平方项是非负数这一性质达到增加题目条件等目的的一种数学方法 .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 The matching method, in mathematics, refers to a mathematic method in which algebraic expressions are completely squared by means of fitting, etc., and then the use of properties such as full squares is nonnegative to achieve the purpose of increasing the condition of the title. The same formula can have Different formula results can be assigned to a flat pattern or multiple flat patterns. The formula’s objects also have diversity, numbers, letters, formulas, functional relationships, etc.
