分式方程是每年各地中考的重要考点之一,也是初中数学中的重要内容,由于这部分知识多、概念多,隐含条件不容易发现,加之学生们解题时审题不细,考虑不周,隐含条件挖掘不到位,因此容易陷入误区,解题时常出现这样或那样的错误,为帮助学生们正确了解分式方程解题时出现的错误,现举例逐一进行剖析,以期引起注意,加以防范,供师生参考.一、去分母时漏乘不含分母的项致错
Fractional equation is one of the important test centers in the middle of every year, and it is also an important part of junior high school mathematics. Because of this part of knowledge, many concepts, implicit conditions are not easy to find, combined with the students solve the problem is not fine, , Implicit conditions are not in place, so easy to fall into errors, problems often appear this or that mistake, to help students correctly understand the fractional equation problem-solving errors, are examples of one by one analysis, in order to attract attention, to be Prevention, for teachers and students.One, to the denominator missed by the non-denominator item is wrong
