近年来各地中考数学命题注意了对同学们思维周密性的考查,可是很多同学在平时解题时往往只满足于求出一解而导致解题不完整,从而出现漏解。造成漏解的原因多种多样,情况复杂,希望引起大家注意并加以克服。一、概念不清易产生漏解例1已知方程x~2+my~(m-1)=8是关于x、y的二元二次方程,求m的值。 In recent years, the mathematics propositions of the local examinations have paid attention to the examination of the students’ thoughtfulness of thinking. However, many students often only content themselves with finding a solution when they solve the problem at the same time, which leads to incomplete solutions, and thus leads to misunderstandings. There are many reasons for misunderstandings and the situation is complex. We hope to attract everyone’s attention and overcome them. First, the concept is not easy to produce leakage solution Example 1 The known equation x~2+my~(m-1)=8 is the binary quadratic equation about x and y, and the value of m is found.
