因式分解是在学习有理数和整式四则运算的基础上进行的.它为以后学习分式运算、解方程和方程组及代数式和三角函数式的恒等变形等知识提供了必要的基础.因此因式分解是中学代数教材的一个重要内容,它具有广泛的基础知识的功能. 由于进行因式分解时要灵活地、综合地运用学过的有关数学基础知识,并且因式分解的途径多,技巧性强,要求逆向性思维较高,而这些对中学生来说具有一定的深广度,所以因式
Factorization is based on the study of rational numbers and integral arithmetic operations. It provides the necessary basis for the subsequent learning of fractional operations, solving equations and equations, and the knowledge of constant deformation of algebraic and trigonometric functions. Decomposition is an important content of middle school algebra teaching materials, it has a wide range of basic knowledge of the function. Due to the factorization, it is necessary to use the basic knowledge of mathematics that has been studied flexibly and comprehensively, and there are many ways to factorize. Strong sex requires higher thinking in reverse, and these have a certain degree of breadth and depth for middle school students.
