所谓不定方程是指方程的个数少于未知量的个数,且未知量又受某些限制(如为整数、正整数等)的一类方程.在初中数学竞赛中,不定方程问题是一类综合性较强的问题,对于此类问题,如能仔细分析,掌握题目的一般规律,找出其隐含条件,或根据其自身特点和已学过的知识,灵活运用一些方法,就能迎刃而解.以下介绍几种常用的方法:
The so-called indefinite equation is the equation of the number of less than the number of unknowns, and unknowns are subject to certain restrictions (such as integers, positive integers, etc.) a class of equations in the junior high school mathematics competition, the problem of indefinite equation is a Class comprehensive strong questions, for such issues, such as careful analysis, grasp the general rules of the problem, find out the implied conditions, or according to their own characteristics and have learned knowledge, use some flexible methods, you can Here are some commonly used methods:
