解无理方程（组）的一些方法技巧孔鸣对于无理方程（组），一般是先乘方脱去根号，然后转化为整式方程（组）求解。如果我们能够根据方程的结构特征，巧妙灵活地运用一些方法技巧，则常常可以使解题过程简化，下面分类举例加以说明。一、观察法例１无理方程（ｘ－１）（ｘ... Some methods of solving irrational equations (groups) Tips for boring For unreasonable equations (groups), the first is to remove the root number from the power and then to convert to the equation (group). If we can use clever and flexible methods and techniques according to the structural features of equations, we can often simplify the problem-solving process. First, observe the law 1 irrational equation (x-1) (x...
