范文三:2014年八年级数学上册同步教案+同步练习--分式 投稿:侯睩睪

第15章分式

第01课分式的基本性质

知识点

一、分式

A的式子叫做分式,其中A和B均为整式,B中含有字母。B

分式是否有意义的识别方法:分式无意义的条件:;分式有意义的条件:;分式为零的条件:;

二、分式的基本性质:分式的分子与分母都,分式的值不变。

(1)分式的分子与分母都乘以(或除以)的整式不能等于零.

(2)要充分理解基本性质中的“都”和“同”这两个字的含义,避免犯只乘分子或分母一项的错误.(3)分式的分子、分母与分式本身的符号,改变其中,分式的值不变.

(4)因为分数线在分式中具有括号的作用,当分子或分母为多项式,要把它看作一个整体变号时,将多项式的各项都改变符号.

三、约分:

根据分式的基本性质,把一个分式的分子与分母的公因式约去,叫做分式的约分。

分式约分的步骤:先,再。

(1)如果分式的分子、分母是单项式,约去分子、分母的系数的最大公约数和相同因式的最低次幂.

(2)如果分式的分子与分母都是多项式时,可先把分子、分母分解因式,然后约去分子与分母的公因式.

(3)当分式的分子或分母的系数是负数时,应先把负号提到分式的前边.

最简分式:分子与分母没有公因式的分式,叫做最简分式。(既约分式)

分子、分母都是乘积形式时,才能约分.

四、通分:

(1)分式通分的意义:根据分式的基本性质,把几个异分母的分式分别化成与原来的分式相等的同分母的分式,叫做分式的通分。

(2)通分的关键是确定几个分式的公分母。

(3)取各分母所有因式的最高次幂的积作公分母,这样的公分母,叫做最简公分母。确定公分母时应注意:系数取,字母因式取。

(4)约分是对一个分式而言,是将分式化简;通分是对几个分式而言,是将分式化繁。

根据分式的基本性质,将分式的分子和分母都乘以同一个数,就可以使它们各项的系数化为整数;这个数显然应取分子、分母中各项系数的最小公倍数.

分子或分母的系数是负数时,󰂪一般先把负号提到分式本身的前面,或先去掉负号.

分子和分母中含有可以分解因式的多项式,应先把它们分解因式,󰂪然后再约去公因式.分式的概念:一般地,形如
