在初中数学中有许多不为零的规定,由于同学们对这些规定不够重视或理解不深,导致解题时常出现错解.下面将可能出现的错误归纳如下,供大家参考.一、分式的分母不能为零例1若代数式(|x|-2)/(x~2-x-2)的值为零,则x的值为().
In junior high school mathematics there are many non-zero provisions, because students do not pay enough attention to these provisions or understanding is not deep, leading to misunderstandings often. The following will be the error can be summarized as follows, for your reference. The denominator can not be zero Example 1 If the value of the algebraic equation (| x | -2) / (x ~ 2-x-2) is zero, the value of x is ().
