(x-y)^3×(y-x)^4+(x-y)^2×(y-x)^5
-(5x+y)-3(2x-3y)(化简)
2(x-y)+3(x+y)2-5(x-y)-8(x+y)2-(x-y)
化简:5(x-y)+2(x+y)-3(x-y)
2(x-y)²-3(x-y)(-y-x)
化简:2(x-y)2-3(y-x)+5(X-Y)2=3(x-y)
[(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)
化简 求值 x-{-5x-[-y+(-x+3y)+x]},其中x=-1,y=-2;
先化简,再求值 [2/3x - 2/x+y(x+y/3x -x-y)]*x/x-y,其中5x+3y=0
((x+2y)x^2+(x-y)(3x-y)-5y^2)÷2x
若3x-5y=0,则x+y/x=(),x-y/y=(),2x-3y/2x+3y=( )
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
化简 (x+2)平方-(x-y)(y-x)是(x+y)平方-(x-y)(y-x)
化简(2x-3y)²-(2x-3y)·(2x3y)+y(6y+5x)
化简:{2/3x-2/(x+y)[(x+y)/3x-x-y]}/(x+y)/x
化简3x-2/(x+y)[(x+y)/3x-x-y]÷(x-y)/x
化简 x-y+(2y²)/(x+y)
化简:[(x+2y)^2-(x+y)(3x-y)-5y^2]/2x
