[(3x+2y)(3x-2y)-(x+2y)(5x-2y)]÷(4x)要步骤[(3x+2y)(3x-2y)-(x+2y)(5x-2y)]÷(4x)要步骤[(3x+2y)(3x-2y)-(x+2y)(5
[(3x +2y)(3x-2y)-(x+2y)(5x-2y)]÷(4x)要步骤
[(3x +2y)(3x-2y)-(x+2y)(5x-2y)]÷(4x)要步骤
[(3x +2y)(3x-2y)-(x+2y)(5x-2y)]÷(4x)要步骤
(9x^2-4y^2-5x^2+4y^2-8xy)/(4x)=(4x^2-8xy)/(4x)=x-2y
vhjk,j,jh,jhjh,
2(x-y)²-3(x-y)(-y-x)
(y-x)^4(x-y)^3+2(x-y)^6(y-x)
(x-y)^3×(y-x)^4+(x-y)^2×(y-x)^5
12(x+y)^3(y-x)/【4(x+y)^2(x-y)】
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,
3x(x-2y)+(x+2y)(2x-y)-3y(y-2x)
2(x-y)+3(x+y)2-5(x-y)-8(x+y)2-(x-y)
3x+y=2 -y/x+y=123x+y=2 (-y/x)+y=12
x(x-y)2-(y-x)3
先化简,再求值 [2/3x - 2/x+y(x+y/3x -x-y)]*x/x-y,其中5x+3y=0
[2/3x-2/x+y(x+y/3x-x-y)]/x-y/x
化简:{2/3x-2/(x+y)[(x+y)/3x-x-y]}/(x+y)/x
计算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
[(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)
(x/x+y +2y/x+y)乘以xy/ x+2y除以(1/x+1/y)(2)(3x^2/4y)^2乘以2y/3x+ x^2/2y^2除以2y^2/x
