分解因式是整式乘法的逆向运用,与整式乘法运算有着密切的联系．通过分解因式的学习,你会体会到逆向思考问题有助于我们发现新知识和深入地研究相关的旧知识．分解因式中包含有两种重要数学思想： 1．类比思想在分解因式的学习中, 我们经历了从分解因数到分解因式的类比过程,类比整式的乘法进行分解因式的探索活动,感受整式乘法与分解因式之间的互逆关系．
The factorization factor is the reverse use of integer multiplication, which is closely related to integer multiplication. By decomposing factorized learning, you will realize that the problem of reverse thinking helps us to discover new knowledge and to study in depth the related old knowledge. Factorization contains two important mathematical ideas: 1. In the study of decomposition factor, we experienced the process of analogy from factorization to factorization, factorial exploration through factorial integer multiplication, and felt the reciprocal relationship between factorization and factorization.
