对于一些涉及看似复杂的数、式子、图形的问题,不少学生往往感觉很难,无从下手,懒得动脑没有动笔就直接放弃.其实只要我们能掌握解决问题的技巧———分解法,就能做到化繁为简.接下来我们来谈谈“分解法”在解题中的应用,所谓“分解法”就是把复杂的问题分解成简单易解答的或已经解决的问题,从而达到解题的目的.分解法主要包括数的分解、式子的分解和图形的分解.一、数的分解
For some involving complex numbers, formulas, graphics problems, many students often feel difficult, can not start, too lazy to give up the brain without writing. In fact, as long as we can master the problem-solving skills --- decomposition method, Then we can talk about “decomposition method ” in the problem-solving application, the so-called “decomposition method ” is the complex problem is decomposed into simple or has been solved Problems, so as to achieve the purpose of solving problems.The decomposition method mainly includes the number of decomposition, the decomposition of the formula and the decomposition of the figure.
