10a(x-y)平方-5b(y-x)x(a-x)(a-y)-y(x-a)(y-a)ab(a-b)-a(b-b)ab(a-b)-a(b-b)x(a-x)(a-y)-y(x-a)(y-a分解因式10a(x

10a(x-y)平方-5b(y-x) x(a-x)(a-y)-y(x-a)(y-a) ab(a-b)-a(b-b)ab(a-b)-a(b-b) x(a-x)(a-y)-y(x-a)(y-a 分解因式
10a(x-y)平方-5b(y-x) x(a-x)(a-y)-y(x-a)(y-a) ab(a-b)-a(b-b)
ab(a-b)-a(b-b) x(a-x)(a-y)-y(x-a)(y-a 分解因式

10a(x-y)平方-5b(y-x) x(a-x)(a-y)-y(x-a)(y-a) ab(a-b)-a(b-b)ab(a-b)-a(b-b) x(a-x)(a-y)-y(x-a)(y-a 分解因式
ab(a-b)-a(b-a)
=ab(a-b)+a(a-b)
=a(a-b)(b+1)
x(a-x)(a-y)-y(x-a)(y-a )
= x(a-x)(a-y)-y(a-x)(a-y )
=(x-y)(a-x)(a-y)
如果本题有什么不明白可以追问,

ab(a-b)-a(b-a)
=ab(a-b)+a(a-b)
=(a-b)(ab+a)

x(a-x)(a-y)-y(x-a)(y-a )
= x(a-x)(a-y)+y(a-x)(a-y )
=(x+y)(a-x)(a-y)

应该是这样写,希望能帮到你。
