化简(x-y)(a+b)-(x-y)(a-b)化简(x-y)(a+b)-(x-y)(a-b)化简(x-y)(a+b)-(x-y)(a-b)(x-y)(a+b)-(x-y)(a-b)=(x-y)[(a+
化简(x-y)(a+b)-(x-y)(a-b)
化简(x-y)(a+b)-(x-y)(a-b)
化简(x-y)(a+b)-(x-y)(a-b)
(x-y)(a+b)-(x-y)(a-b)
=(x-y)[(a+b)-(a-b)]
=(x-y)*2b
=2bx-2by
=(x-y)(a+b-a+b)
=2b(x-y)
化简(x-y)(a+b)-(x-y)(a-b)
(x+y)-(a-b)(x+y)因式分解
因式分解 a(y-x)-b(x-y)
(5)a(x+y)-b(x+y)-x-y因式分解
通分:-x/a(x-y) ,y/b(y-x)
通分x/a(x-y),y/b(y-x)
通分 a/(y-x)^2,b/(x-y)(x+y)
因式分解a(x-y)+b(y-x)+(2x-y)
化简x²/(y-x)-y²/(y-x)的结果是要求写具体过程、A -x-y B y-x C x-y D x+y.
(a-b)(x-y)-(b-a)(x+y)怎么算
(a+b)(x+y)-(a+b)(x-y)分解因式
(a-b)(x-y)-(b-a)(x+y)因式分解
(a+b)(x+y)-(b+a)(y-x)因式分解快
[a-b][x-y]-[b-a][x+y]的解法
(a-b)(x-y)+(b-a)(y-x)
分解因式：(a-b)(x-y)-(b-a)(x+y)
(a-b)(x-y)-(b-a)(x y)如何解题
(a-b)(x-y)-(b-a)(x+y)
