无理方程在初中教学中是作为能化为一次或二次的方程的一种方程类型来研究的。由于教材难度较大,课时太少(约2课时),学生对无理方程学得较差,对稍难一些的题往往束手无策。本文就解无理方程的一些方法和技巧进行探讨,以供教学和总复习时参考。 The unreasonable equation is studied in junior high school as an equation type that can be transformed into one or two equations. Due to the difficulty of teaching materials, too little class time (about 2 hours), students have poor learning of irrational equations, often difficult to help at some difficult problems. This article discusses some of the methods and techniques for solving irrational equations for reference when teaching and general reviewing.
