利用平方处理数学问题的方法叫做平方法.它的初始应用是在初中解无理方程时开始的.先入为主,一些学生在后来只注意到二次根号时才用平方法,实际上并非如此,大量的不含根号的题常用平方法,掌握了平方法对提高解题是大有好处的,现总结如下. The method of using the square to solve mathematical problems is called the flat method, and its initial application begins when the junior middle school solution to the irrational equation is preconceived, and some students later noticed the square root method only when they were quadratic roots. In fact, The root of the problem without the usual flat method, mastered the flat method to improve the problem-solving is of great benefit, are summarized as follows.
