韦达定理在中学数学的方程、函数、不等式中都有着广泛的应用。本文概述运用韦达定理解题时应注意的问题:如隐含条件、充分必要性等,应用时要认真考虑能否直接运用,要加以鉴别,才不谬误;最后,根据例析,总结归纳运用韦达定理解题的一些规律。1直接运用定理 Vedic theorem has a wide range of applications in the equations, functions and inequalities of mathematics in middle schools. This article summarizes the problems that should be noticed when using Vedantine to solve the problem: If implied conditions, the necessary and sufficient, serious consideration should be given to the application can be applied, to be identified, not fallacious; Finally, based on the analysis, summarized Use Vedanta to solve some problems. 1 direct application of the theorem
