二次根式的化简是二次根式一章中的重要内容,也是中考和数学竞赛中比较常见的题型.对于特殊的二次根式的化简,除了掌握基本概念和运算法则外,还要掌握一些特殊的方法和技巧.现将二次根式化简中的几种技巧和方法作一归纳,供同学们参考. 一、配方法配方法是数学中的一种重要方法.根式化简中,通过配方将被开方数(式)化为完全平方数(式),从而化简根式.
The simplification of secondary roots is an important part of the secondary roots chapter. It is also a common question in the middle school exams and math contests. In addition to the basic concepts and algorithms, a special secondary root simplification is required. Grasp some special methods and techniques. Now sum up several techniques and methods in the secondary root Simplification for students to refer to. First, matching method is an important method in mathematics. Root Simplification The formulation will be converted into the square number (formula) by the number of squares (formula), thereby simplifying the root formula.
