初一下整式的除法练习题,求过程。 1.[(x+y)(x-y)-(x+y)²-2y(x-y)-2xy]÷xy 2.(7a² b²c-5abc²)÷ab 3.(xy²+1/4y²-1/2y)÷1/2y
4.[(x-1)(x+2)+2]÷
5.(6an+2的次方-9an+1次方+3an-1次方)÷3an-1次方
6.(x²-2xy)·9x²-(9xy三次方-12x四次方y²)÷3xy
7.[(x+y)(x-y)-(x-y)²+2y(x-y)]÷4y 展开
4.[(x-1)(x+2)+2]÷
5.(6an+2的次方-9an+1次方+3an-1次方)÷3an-1次方
6.(x²-2xy)·9x²-(9xy三次方-12x四次方y²)÷3xy
7.[(x+y)(x-y)-(x-y)²+2y(x-y)]÷4y 展开
