绝对值问题是高中的重要学习内容,贯穿于整个高中数学学习中,一些绝对值问题若仅仅依据绝对值的定义分类讨论去掉绝对值符号的一般解法去处理,可能较为繁琐,因此,我们有必要去关注一些简解。一、紧扣概念挖掘隐含条件 The absolute value problem is an important learning content in high school. Throughout the entire high school mathematics learning, some absolute value problems may be cumbersome if they are classified according to the definition of absolute value only to deal with the general solution of removing absolute symbols. Therefore, we need To pay attention to some brief. First, closely linked to the concept of mining implied conditions
