如果本题有什么不明白可以追问,
【2(x-y)(x-y)(x-y)-8(x-y)(x-y)(x+y)+6y(x-y)(x-y)]/2(x-y)(x-y)
(x+y)^2+6(x+y)+9
x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2
(x-2y)^2-6(2y-x)(x+y)+9(x+y)^2因式分解
81/8*(-x-y)^6*(x-y)^3*4/9(x+y)^4*(y-x)^2
计算(x-y)^7÷(y-x)^6+9-x-y)^3÷(x+y)^2
9(x+y)-2(x+y)-6(x+y)+18(x+y)合并同类项
合并同类项：9(x+y)-2(x+y)-6(x+y)+18(x+y)
化简y(x+y)+(x+y)(x-y)-x^2
化简：x-y/x+3y÷x^-y^2/x^2+6xy+9y^2-(xy/x+y)
(x+y)(x-y)-(x-y)^2如题 (x+y)(x-y)-(x-y)^2
计算:(x-y)^2*(y-x)^2*(x-y)^6
6(x+y)2-2(x-y)(x+y)因式分解
