分式方程出题时出现增根与无解时该如何区分,常见的三种情况:1.无解=增根.2.无解>增根.3.无解≠增根.在初二数学分式这一章,解分式方程中会出现增根的现象而导致分式方程无解,因此解分式方程时必须检验.而同学们在做相关的练习题时,有时会遇到无解,有时会遇到增根,那么无解与增根到底有怎样的区别呢?(一)无解=增根有时候题目中出现的无解与增根
There are three kinds of common situations when there is a problem of multiplication equation and problem-free solution. There are three common cases: 1. No solution = root increase 2. No solution> root increase 3. No solution ≠ root increase In the first two Mathematical fraction of this chapter, resolving equations will appear in the root phenomenon led to the fractional equation has no solution, so the solution equation must be tested, while students do related exercises, sometimes encountered No solution, and sometimes will encounter root, then no solution and what is the difference between the root? In (1) no solution = root Sometimes there is no solution and the root of the problem
