将多项式2ab^2(x-y)^m+1-6a^2b(x-y)^m因式分解为

问题描述:

将多项式2ab^2(x-y)^m+1-6a^2b(x-y)^m因式分解为

2ab^2(x-y)^m+1-6a^2b(x-y)^m
=2ab[(x-y)^m](b-3a)过程- -这就是所有过程了啊,提出公因式2ab(x-y)^m就行了,第一项只剩b,第二项剩-3a。3ab^(2)(x-y)^(m+1)-6a^(2)b(x-y)^m题目写错了2ab²(x-y)^m+1-6a²b(x-y)^m=2ab[(x-y)^m](b-3a) 一样的(x-y)^(m+1)这里不是有个m+1莫o 2ab²(x-y)^(m+1)-6a²b(x-y)^m=2ab[(x-y)^m][b(x-y)-3a]=2ab[(x-y)^m](bx-by-3a)
