现在我们一起跟着渔人到这个世外桃源去看看。

本文大约写于宋永初二年(421年)，陶渊明约57岁。

1.1 多项式的因式分解教学目标1．了解分解因式的意义，以及它与整式乘法的相互关系．2．感受因式分解在解决相关问题中的作用．3．通过因式分解培养学生逆向思维的能力。

重点与难点重点：理解分解因式的意义，X地辨析整式乘法与分解因式这两种变形。

难点：对分解因式与整式关系的理解教学过程一、创设情境，导入新课1 回忆整式乘法和乘法公式填空：计算：(1)2ab(3a+4b-1)=_________, 〔2〕〔a+2b〕(2a-b)=__________(3)〔x-2y〕(x+2y)=__________;(4) =_____________(5) =________ lspjy 分站2 你会解方程：吗？估量学生会想到两种做法：〔1〕一是用平方根的定义，〔2〕二是：解：〔x+1〕(x-1)=0,依据两个因式相乘等于0，必有一个因式等于0，得到：x+1=0或者x-1=0,因此：得x=1或-1指出：把叫因式分解，为什么要把一个多项式因式分解呢？这节课我们来学习这个问题。

二合作交流，探究新知1 因式的概念〔1〕说一说： 6=2&215;___, ,〔2〕指出：对于6与2，有整数3使得6=2&215;3，我们把2叫6的一个因数，同理,3也是6的一个因数。

类似的：对于整式与x+2,有整式x-1使得，我们把x+2叫多项式的一个因式，同理，x-2也叫多项式的一个因式。

你能说说什么叫因式吗？一般地，对于两个多项式f与g,如果有多项式h使得f=gh,那么我们把g叫f 的一个因式，同样，h也是f的一个因式。

〔3〕考考你：你能说出下面多项式有什么因式吗？A ab+ac,BC D2 因式分解的概念〔1〕指出;一般地，把一个含字母的多项式表示成假设干个均含字母的多项式的乘积的形式，称为把这个多项式因式分解。

〔2〕考考你：下面变形叫因式分解吗？E =F =说明：因式分解的对象是含有字母的多项式因此 A 不是因式分解，因式分解的目的是把含字母的多项式化成均含字母的乘积的形式，因此B不是，因为不是多项式。
