(1)(x^2/x)-y-x-y(2)(a/a-b)-(a/a+b)-(2b^2/a^2-b^2)(1)(x^2/x)-y-x-y(2)(a/a-b)-(a/a+b)-(2b^2/a^2-b^2)(1
(1)(x^2/x)-y-x-y(2)(a/a-b)-(a/a+b)-(2b^2/a^2-b^2)
(1)(x^2/x)-y-x-y
(2)(a/a-b)-(a/a+b)-(2b^2/a^2-b^2)
(1)(x^2/x)-y-x-y(2)(a/a-b)-(a/a+b)-(2b^2/a^2-b^2)
（1)x^2/x)-y-x-y
=x-y-x-y
=-2y
(2)(a/a-b)-(a/a+b)-(2b^2/a^2-b^2)
=a(a+b-a+b)/(a^2-b^2)-(2b^2/a^2-b^2)
=2b/（a+b）
第一题不是等于2y吧
^ 是什么意思？
(1) -2y
(1)(x^2/x)-y-x-y
=x-x-2y
+-2y
(2)(a/a-b)-(a/a+b)-(2b^2/a^-b^2)
=2b/(a+b)
楼主有时间上网提问不如好好练习
x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2
[(-x-y)(-x+y)-(x+y)^2-x(y-y^2)}÷1/2y
化简y(x+y)+(x+y)(x-y)-x^2
因式分解x(x+y)(x-y)-x(x+y)^2
1、y-x/x²-y²2、(x-y)(y-z)(z-x)/(z-y)(y-x)(x-z)
(x+y)(x-y)-(x-y)^2如题 (x+y)(x-y)-(x-y)^2
(x/x+y-x/y-x-2xy/x.x-y.y)/(1/x-1/y) 分式化简
(x-y)(2x-y-1)
【2(x-y)(x-y)(x-y)-8(x-y)(x-y)(x+y)+6y(x-y)(x-y)]/2(x-y)(x-y)
x²/xy-x/y 3x/4x+y - x-2y/4x+y (1-y/y+x)÷x/y²-x²
x^2(x-y)+(y-x)
x(x-y)2-(y-x)3
已知x+y=a,2x-y=-2a,求[（x/y-y/x)/(x+y)-x(1/x-1/y)]/[(x+1)/y]的值
若2/x-1/y=3,求[y/x-y/x-y(x-y/x-x+y)]/x-2y/x的值
2y(x+二分之一y)-[(x+y)(x-y)+2y(y+x)],其中|x-1|=2
（x-y)(x+y)-(x+y)^2+2y(y-x),其中x=1,y=3.
计算:y-x分之x+y+x-y分之y-y-x分之2x-y
【(x-y)^2+(x+y)(x-y)】除以 2x
