含参变量的方程的三种基本解法陕西省山阳中学吴克成陈淑芳直接化归法，参变量分离法，函数性质（或图象）法是解决含有参变量的方程根的分布问题的基本方法．要有效地解决这类综合性强、涉及面广、能力要求高的问题，就必须掌握这三种方法．一、直接化归法就是把原方程的...
Three Basic Solutions for the Equations with Parametric Variables Wu Kecheng, Chen Shufang, Shanyang Middle School, Shannxi Province, direct conversion, parametric variable separation, function property (or image) method is the basic method to solve the problem of the distribution of the roots of the equations with parametric variables. . To effectively solve this kind of comprehensive, wide-ranging, high-capacity requirements, we must master these three methods. First, direct translation is the original equation...
