x^3y+3x-3x^2y^2-6yx^3y+3x-3x^2y^2-6yx^3y+3x-3x^2y^2-6y刚才说了,这个题目有问题改一下吧x^3y+3x-2x^2y^2-6y=x³y-2x
x^3y+3x-3x^2y^2-6y
x^3y+3x-3x^2y^2-6y
x^3y+3x-3x^2y^2-6y
刚才说了,这个题目有问题
改一下吧
x^3y+3x-2x^2y^2-6y
=x³y-2x²y²+3x-6y
=x²y(x-2y)+3(x-2y)
=(x-2y)(x²y+3)
x³y+3x-2x²y²-6y
=x(x²y+3)-2y(x²y+3)
=(x-2y)(x²y+3)

[2(x-y)^5-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2[2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2
3y/x*x-y*y+x/x*x-2xy+y*y+6y*y/x*x*x-x*x*y-xy*y+y*y*y等于多少?
[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
因式分解3x^2(x-y)+6x(y-x)
【2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2】/2(x-y)^2=
[(3x+y)(x-y)-(2x+3y)(x-y)]*(x-y)
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
2(2x+3y)(3x+2y)-(6x-y)(2x-5y)
x+y/2+x-y/6=5 2(x+y)-3(x-y)=-2
x+y/2+x-y/3=6,4(x+y)-3(x-y)=-20
{(x+y)/2+(x-y)/3=6 4(x+y)-3(x-y)=-20
4(x+y)-3(x-y)=-20,2/x+y+3/x-y=6
