分式是八年级代数中一种重要的代数式,将一个复杂的分式恒等变形化为一个简单的代数式,我们就称为化简,而分式化简求值是中考中常考的一类试题,是要求学生必须掌握的一项基本数学技能,要解决好这类试题,需要学生有较好的分式运算技巧。下面就一道中考题,介绍解分式常用的几种方法。 Fractional is an important algebra in eighth grade algebra, a complex fractional identity transformation into a simple algebra, we call reduction, and fractional reduction of the value of the examination is often a type of test Questions, is to ask students to master a basic mathematical skills, to solve such questions, students need to have better fractional computing skills. Below a test in the exam, introduced several methods commonly used solution points.
