整式的运算与因式分解在数学中的地位和作用是一样的,既是进一步学习分式、一元二次方程、二次函数的基础,又是解决综合性问题的基本的、必需的工具.在中招试卷中,绝大部分试题都涉及这部分知识,其中单独考查该知识点的题目以中等题、容易题居多.但由于相关概念、运算法则较多,易混淆,如果掌握不牢极易丢分.因此,对该部分知识的学习应做到准确理解,牢固掌握,以达到灵活运用的目的. The operation and factorization of integer formulas are the same in mathematics, and they are not only the basis for further study of fractions, quadratic equations, quadratic functions, but also basic and necessary tools for solving comprehensive problems. In the test paper, most of the questions involved in this part of the knowledge, including the examination of the knowledge point of the problem to a medium title, easy questions are mostly. However, due to the relevant concepts, algorithms are more confusing, if not easy to master Loss points. Therefore, the study of this part of the knowledge should be accurately understood, firmly grasped, in order to achieve the purpose of flexible use.
