(x-y)^3×(y-x)^4+(x-y)^2×(y-x)^5
2(x-y)+3(x+y)2-5(x-y)-8(x+y)2-(x-y)
2(x-y)²-3(x-y)(-y-x)
[(x+y)(x-y)-(x-y)的平方+2y(x-y)]除以(4y)请帮我一下写两道计算题[(x+y)(x-y)-(x-y)的平方+2y(x-y)]除以(4y)[(3x+2y)(3x-2y)-(x+2y)(5x-2y)]除以(4x)
先化简,再求值 [2/3x - 2/x+y(x+y/3x -x-y)]*x/x-y,其中5x+3y=0
若3x-5y=0,则x+y/x=(),x-y/y=(),2x-3y/2x+3y=( )
((x+2y)x^2+(x-y)(3x-y)-5y^2)÷2x
若x-y分之x+y=3,求式子x+y分之5(x-y)—2(x-y)分之x+y的值
(5)若x/2=y/3(y不为0)则x/y=____,x+y/y=___,y/x-y=___.
(y-x)^4(x-y)^3+2(x-y)^6(y-x)
12(x+y)^3(y-x)/【4(x+y)^2(x-y)】
(x+y)^6/(x+y)^4-(x-y)^5/(x-y)^3 化简 ..
计算(x-y)^2×(x-y)^3×(y-x)×(y-x)^2
(x+y)/2- x-y/2=6 3(x+y)=4(x-y)
2分之x+y+3分之x-y;4(x+y)-(x-y)谢谢了,
