快速分解因式的诀窍是“方法熟”、“方向明”、“技巧灵”这九个字．所谓“方法熟”，就是熟悉因式分解的四种基本方法；所谓“方向明”，就是一拿到题目便能确定应用什么方法分解；所谓“技巧灵”，就是能对题目进行适当的变形，以便创造条件进行分解．本文以中考题或竞赛题?
The fast decomposing factors are the nine words “method familiar”, “direction clear”, and “skillful spirit”. The so-called “method familiarity” is familiar with the four basic methods of factorization; the so-called “direction-oriented” means that you can determine what method to apply when you get the problem; the so-called “crafty spirit” is the ability to properly deform the problem. In order to create conditions for decomposition. This paper takes the exam questions or contest questions?
