[a-b][x-y]-[b-a][x+y]的解法
[a-b][x-y]-[b-a][x+y]的解法
[a-b][x-y]-[b-a][x+y]的解法
[a-b][x-y]-[b-a][x+y]
=[a-b][x-y]+[a-b][x+y]
=[a-b][x-y+x+y]
=2x[a-b]
原式=(a-b)(x-y)+(a-b)(x+y)
=(a-b)(x-y+x+y)
=2x(a-b)
=(a-b)(x-y)+(a-b)(x+y)
=(a-b)(x-y+x+y)
=2x(a-b)
原式
=(a-b)(x-y)＋(a-b)(x＋y)
=(a-b)(x-y＋x＋y)
=(a-b)2x
=2ax-2bx
(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)
(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
化简(x-y)(a+b)-(x-y)(a-b)
(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)
因式分解,（a-b)(x-y)-(b-a)(x-y)（a-b)(x-y)-(b-a)(x+y）
