形如F(x)·()≥0的一类不等式,学生求解时,常常将其转化为不等式组而通过解这个不等式组求原不等式的解集可能导致漏解,这个问题,文[1]已作了详尽的剖析,本文将继续介绍这类不 A class of inequalities such as F(x)·() ≥ 0 may be converted into an inequality group when the student solves the solution, and solving the solution set of the original inequality by solving the inequality group may lead to a missed solution. This problem [1]. ] has made a thorough analysis, this article will continue to introduce this type of not
