【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/x-x+y/y-(x+y)(x-y)/y² y/x=2
(x-y)²-8(x-y-2)
16-8(x-y)+(x-y)2
-8(y-x)^2×(x-y)
(2x+y)²+(x+3y)(x-3y)-x(5x+8y)因式分解
[2(x-y)^5-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2[2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2
化简y(x+y)+(x+y)(x-y)-x^2
【2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2】/2(x-y)^2=
(x-8y)(x+y)
(x+y)(x-y)-(x-y)^2如题 (x+y)(x-y)-(x-y)^2
2x/(x-8y)(x+8y)-(x+8y)/ (x-8y)(x+8y)怎麼计算了 详细
化简(2x/(x+y)-4x/(y-x))/8x(x^2-y^2)得
因式分解x(x+y)(x-y)-x(x+y)^2
12y(x-y)^2-8(x-y)^3=?
-(x-y)^2-2(y-x)^2-5(x-y)^2+8(x-y)^2化简
4x-3y/x-2y÷6y-8x/y-2x
(x-y)^2+7(x+y)-11(x-y)^2-8(x+y),先化简.再求值
