(a-b)^2(x-y)-(b-a)(y-x)^2因式分解哦!

(x+y)(a-2b) 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)(a^2+b^2)(a+b)[(x-y)^2-(x-y)(x+y)]/(2y) (x+y)-(a-b)(x+y)因式分解 因式分解 a(y-x)-b(x-y) a(x-y)(x+y)-b(y-x)(x+y)-c(x-y)^2(y+x)提取公因式 (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）
