人教版八年级下册数学课本知识点归纳新编

人教版八年级下册数学 知识点归纳 第十六章 分式 一、分式 1. 分式:如果A 、B 表示两个整式,并且B 中含有字母,那么式子B A 叫做分式。 (分式有意义的条件是分母不为零,分式值为零的条件分子为零且分母不为零 ) 2. 分式的基本性质:分式的分子与分母同乘(或除)以一个不等于0的整式,分式的值不变。用式子表示如下: (C ≠0) 其中A,B,C 是整式 3.最简公分母:取各分母的所有因式的最高次幂的积做公分母,它叫做最简公分母 4.通分:分子和分母同乘最简公分母,不改变分式值,把几个整式化成相同分母的分式。这个过程叫通分。(分母为多项式时要分解因式) 5.约分:约去分子和分母的公因式,不改变分式值,这个过程叫约分。 二、分式的运算 1.分式乘法法则:分式乘分式,用分子的积作为积的分子,分母的积作为分母。 2.分式除法法则:分式除以分式,把除式的分子、分母颠倒位置后,与被除式相乘。 上述法则可以用式子表示: 3分式乘方法则:一般地,当n 为正整数时 这就是说, 分式乘方要把分子、分母分别乘方 C B C A B A ??=C B C A B A ÷÷=bc ad c d b a d c b a bd ac d c b a =?=÷=?;n n n b a b a =)(

4.分式的加减法则:同分母的分式相加减,分母不变,把分子相加减。 异分母的分式相加减,先通分,变为同分母分式,然后再加减。 上述法则可用以下式子表示:,a b a b a c a d bc ad bc c c c b d bd bd bd ±±±=±=±= 5.整数指数幂 1.任何一个不等于0的数的0次幂等于1, 即)0(10≠=a a ; 当n 为正整数时,n n a a 1 =- ()0≠a ,也就是说a n (a≠0)是a -n 的倒数。 正整数指数幂运算性质也可以推广到整数指数幂.(m,n 是整数) (1)同底数的幂的乘法:n m n m a a a +=?; (2)幂的乘方:mn n m a a =)(; (3)积的乘方:n n n b a ab =)(; (4)同底数的幂的除法:n m n m a a a -=÷( a ≠0); (5)商的乘方:n n n b a b a =)(( n 是正整数);(b ≠0) 三、分式方程 1. 分式方程:分母中含未知数的方程叫分式方程。 (解分式方程的过程,实质上是将方程两边同乘以一个整式(最简公分母),把分式方程转化为整式方程。解分式方程时,方程两边同乘以最简公分母时,最简公分母有可能为0,这样就产生了增根,因此分式方程一定要验根。) 2.解分式方程的步骤 :(1)能化简的先化简(2)方程两边同乘以最简公分母,化为整式方程;(3)解整式方程;(4)验根。 3.分式方程检验方法:将整式方程的解带入最简公分母,如果最简公分母的值不为0,则整式方程的解是原分式方程的解;否则,这个解不是原分式方程的解。 四、列方程应用题 1.列方程应用题的步骤是什么?(1)审;(2)设;(3)列;(4)解;(5)答。 2.应用题有几种类型;基本公式是什么?基本上有五种:
