如何提高学生的解题能力?我认为让学生掌握一些带一般性的解题方法是一个重要的方面。下面介绍解代数题中经常使用的几个方法。一、“零点”分段法在解析式化简,解方程(或不等式),作函数图象等问题中,如遇有绝对值符号,就需要讨论,把绝对值符号去掉,使问题简化。而化简形如|f_1(x)|±|f_2(x)|±……±|f_k(x)| How to improve student’s problem-solving abilities? I think it is an important aspect for students to have some general solutions. The following are some of the frequently used methods for solving algebraic problems. First, the “zero” subsection method in the analytical simplified, solve the equation (or inequality), function image and other issues, such as the case of absolute value, you need to discuss, remove the absolute value of the symbol, so that the problem is simplified. Simplify the shape such as |f_1(x)|±|f_2(x)|±......±|f_k(x)|
