原式={[x2-(2y-3/2)2]+4y2-6y+1/12}÷(1/3)
=(x2-4y2+6y-9/4+4y2-6y+1/12)÷(1/3)
=(x2-9/4+1/12)×3=-3.5
其实这道题跟y一点关系都没有
很简单嘛
x(x-y)2-(y-x)3
[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
计算:x+2y/x-y+2x/y-x-3y/x-y
化简:(x-3y)(x+y)-(x-2y)(x+2y)-(x-y)平方
[(3x+y)(x-y)-(2x+3y)(x-y)]*(x-y)
2X(2X-3Y)-3Y(X+Y)
(-2x y)^2-(3y-x)(-x-3y)
(x+2y)^2-(x+y)(3x-y)
计算(x+y)(x+y)^2(-x-y)^3
化简:5(x-y)+2(x+y)-3(x-y)
3x(x-y)+2y(x-y) 计算
化简3(x-y)-7(x--y)+2(y-x)
因式分解:3x(x-y)+2y(y-x)
(x-y)^3×(x-y)^2×(y-x)
分解因式:3x(y-x)-2y(x-y)
