Discussion on the problem of equation with roots
SUN Yanjun
Abstract：The problem of equation howing roots is a common problem in advanced mathematics,which often appears in many proof or discussion questions.It is also a common type of question in the postgraduate entrance examination.There are many types of such problems,and the difficulty is relatively large.However,the content involved in the textbook is very limited,and the relevant literature deals with such problems,and the method is single,which is difficult for students to grasp.Therefore,how to choose the right method is the key to solving this kind of problem.In the process of solving the problem,according to the conditions of the problem and the characteristics of the conclusion,by reverse analysis,comprehensive application of the basic principles of mathematics,choosing the right method,some complex problems will be easily solved.This paper will analyze the characteristics of this kind of problems,summarize the rules,and give several kinds of common question types and common solving methods,to provide a certain theoretical basis for this kind of problems.
