1、复习:整式知识网络及考点(一)1、代数式用运算符号把数或表示数的字母连接而成的式子叫做代数式。单独的一个数或一个字母也是代数式。2、单项式只含有数字与字母的积的代数式叫做单项式。注意:单项式是由系数、字母、字母的指数构成的,其中系数不能用带分数表示,如ba2314,这种表示就是错误的,应写成ba2313。一个单项式中,所有字母的指数的和叫做这个单项式的次数。如cba235是 6 次单项式。3、多项式几个单项式的和叫做多项式。其中每个单项式叫做这个多项式的项。多项式中不含字母的项叫做常数项。多项式中次数最高的项的次数,叫做这个多项式的次数。单项式和多项式统称整式。用数值代替代数式中的字母,按照代
2、数式指明的运算,计算出结果,叫做代数式的值。注意:(1)求代数式的值,一般是先将代数式化简,然后再将字母的取值代入。(2)求代数式的值,有时求不出其字母的值,需要利用技巧,“整体”代入。4、同类项所有字母相同,并且相同字母的指数也分别相同的单项式叫做同类项。几个常数项也是同类项。5、去括号法则(1)括号前是“+”,把括号和它前面的“+”号一起去掉,括号里各项都不变号。(2)括号前是“”,把括号和它前面的“”号一起去掉,括号里各项都变号。6、整式的运算法则整式的加减法:(1)去括号;(2)合并同类项。整式的乘法:),(都是正整数nmaaanmnm),(都是正整数)(nmaamnnm)()(都是正
3、整数nbaabnnn22)(bababa2222)(bababa2222)(bababa整式的除法:)0,(anmaaanmnm都是正整数【注意】:(1)单项式乘单项式的结果仍然是单项式。(2)单项式与多项式相乘,结果是一个多项式,其项数与因式中多项式的项数相同。(3)计算时要注意符号问题,多项式的每一项都包括它前面的符号,同时还要注意单项式的符号。(4)多项式与多项式相乘的展开式中,有同类项的要合并同类项。(5)公式中的字母可以表示数,也可以表示单项式或多项式。(6)),0(1);0(10为正整数paaaaapp(7)多项式除以单项式,先把这个多项式的每一项除以这个单项式,再把所得的商相加,
4、单项式除以多项式是不能这么计算的。(二)整式的运算知识点 1:整式的加减【典例精析】例 1:判断下列式子是单项式,还是多项式,单项式说出它的系数、次数;多项式说出它是几次几项式?6xy,2321xyz,6,33xy z例 2:下列各题中的两项是不是同类项?为什么?(1)0.2x2y 与 0.2xy2;(2)4abc 与 ac(3)mn 与 mn(4)124 与 12(5)0.25st与 ts(6)2x2与 2x3.思路点拨:本题考查的是同类项概念的知识.同类项的形式特征是:字母相同,且相同字母的次数也分别相同,判断同类项无须考虑系数.所有的常数项都是同类项.例 3:先去括号,再合并同类项:23
5、223335531(4)5522242abaa babaa思路点拨:本题考查了去括号、合并同类项的知识.观察到本题即有小括号,又有中括号,所以要先去小括号,再去中括号.去完括号后,再合并同类项.【跟踪练习】1下列说法中正确的是()A2t不是整式;B.yx33的次数是4;Cab4与xy4是同类项;Dy1是单项式2ab 减去22baba等于()A.222babaB.222babaC.222baba;D.222baba3.化简221aa的结果是()A41aB41aC1D14.已知一个多项式与239xx的和等于2341xx,则这个多项式是()A51xB51xC131xD131x5.若523mxy与3n
