配方法是中数里恒等变形的重要方法之一,也是中学生应该掌握的基本技能之一。在教学一元二次方程求根公式时学生便开始接触到这一方法。此后在代数、三角、解析几何的学习中又要求学生能应用自如。在各阶段的教学及总复习时,如果能从总结一种数学方法所能解决的不同问题着眼,加以归纳小结,这对于学生在自觉运用中形成熟练技巧是有好处的。下面来谈配方法的一些应用,供参考。
The method of matching is one of the important methods of equal deformation in the middle number, and it is also one of the basic skills that middle school students should master. The student began to come into contact with this method when teaching the quadratic formula for solving the quadratic equation. Later, in algebra, trigonometry, and analytic geometry, students are required to apply freely. In each stage of the teaching and general review, if we can sum up the summary of the different problems that can be solved by a mathematical method, summarizing the summary, this is beneficial to the students in the conscious use of the formation of skilled techniques. Below to talk about some applications with the method for reference.
