数学思想方法是数学的灵魂.现对一元二次方程蕴涵的主要数学思想进行提炼.一、方程思想和转化思想解一元二次方程实际上是转化为解一元一次方程,达到降次的目的.一元二次方程的解法——直接开平方法、配方法、公式法、因式分解法,都是运用了“转化”的思想,把待解决的问题(解一元二次方程),
Mathematical thinking method is the soul of mathematics. Now the main mathematical ideas implied by the quadratic equation of a quadratic refinement .One, the ideological and transformational ideological solutionUnit a quadratic equation is actually converted to a solution to a dollar equation, to achieve the purpose of reduction. The solution of the quadratic equation - the method of direct Kaiping, the method of formulation, the method of formula and the method of factorization, all make use of the idea of “transformation”, and solve the problem to be solved (solving a quadratic equation)
