=x(x-y)(a-b)+y(x-y)(b-a)
=x(x-y)(a-b)+y(x-y)(a-b)
=(x-y)(a-b)(x+y)本回答被提问者采纳
=x(x-y)(a-b)-y(x-y)(a-b)
=(a-b)(x-y)²
x(x-y)(a-b)-y(y-x)(b-a)
全部乘出来然后因式分解，变成a(x-y)^2-b(x+y)^2
X(X-Y)(a-b)-Y(Y-x)(b-a)
X(X-Y)(a-b)-Y(Y-x)(b-a)=x(x-y)(a-b)+y(x-y)(b-a)=x(x-y)(a-b)+y(x-y)(a-b)=(x-y)(a-b)(x+y)
因式分解x(x-y)(a-b)-y(y-x)(b-a)
1、x（x-y）（a-b）-y（y-x）（b-a）=x（x-y）（a-b）-y（x-y）（a-b）=(a-b)(x-y)^2
x(x-y)(a-b)-y(y-x)(b-a)用因式分解
x（x-y）（a-b）-y（y-x）（b-a）=x（x-y）（a-b）-y（x-y）（a-b)=（x-y）（x-y）（a-b）=（x-y）^2（a-b）6m^2n-5n^2m+30m^2n^2 =mn(6m-5n+30mn)10a(x-y)^2-5ab(y-x)^3 =5a(x-y)^2(2-b(y-x))=5a(x-y)^2(2-by+bx)...
x(x-y)(a-b)-y(y-x)(b-a)分解因式的结果为
x（x-y）（a-b）-y（y-x）（b-a）=x（x-y）（a-b）-y（x-y）（a-b）=(x-y)(x-y)(a-b)=(x-y)²(a-b)
x(x减y)(a减b)减y(y减x)(b减a)
结果应该是(a-b)(x-y)2即(a-b)乘（x-y)的平方
x(x-y)²(a-b)-(y-x)^3(b-a) 因式分解
原式=x(x-y)²(a-b)-(x-y)³(a-b)=(x-y)²(a-b)[x-(x-y)]=y(x-y)²(a-b)
化简向量(x-y)(a+b)-(x-y)(a-b)

因式分解:(a-b)(x-y)-(b-a)(x+y)的答案是什么?
原式= (a-b)(x-y)+(a-b)(x+y)=(a-b)(x-y+x+y)=(a-b)2x
