2011年7月22日、23日举办的第二届陈省身杯数学奥林匹克第6题,是一道三元整式代数不等式试题,其系数看似复杂,其实构思独特,给人以多方面的启迪,本文给出该试题的简证,并对该试题进行合理的推广探究,供参考.题目对任意的 The 2nd Chernia Mathematical Olympiad Question 6, which was held on July 22 and 23, 2011, is a triad integral algebraic inequality test. The coefficient seems to be complicated. In fact, it has a unique concept and gives people inspiration in many aspects. Given a brief description of the test questions, and a reasonable promotion of the test inquiry, for reference.
