1/2x^3y-2^2y^2+2xy^3因式分解1/2x^3y-2^2y^2+2xy^3因式分解1/2x^3y-2^2y^2+2xy^3因式分解1/2x^3y-2x^2y^2+2xy^3(题目是这样的
1/2x^3y-2^2y^2+2xy^3因式分解
1/2x^3y-2^2y^2+2xy^3因式分解
1/2x^3y-2^2y^2+2xy^3因式分解
1/2x^3y-2x^2y^2+2xy^3(题目是这样的吗 )
=1/2xy(x^2-4xy+4y^2)
=1/xy(x-2y)^2
1、(-7x^y)(2x^y-3xy^3+xy) 2、((x-y)^6)/((y-x)^3)/(x-y)
X^Y-2XY^2+y^3
若1/x-1/y=2,求3x-2xy-3y/x-xy-y的值3x-2xy-3y/x-xy-y 不好意思,是3x-2xy-3y/x-2xy-y
因式分解x^2y^2+x^2y+xy^2+3xy+x+y+1
因式分解:12xy^2(y-x)+xy^3(x-y)+4x^2y(x-y)
(-1/3xy)^2•[xy(2x-y)-2x(xy-y^2)]
xy(xy+1)+xy+3-2(x+y+1/2)-(x+y-1)^2因式分解
计算3xy[2xy-x(y-2)+x-1]
(-3分之1xy)的平方×[xy(2x-y)-2x(xy-y的平方)]
x^2-xy-6y^2+3xy+y+2
XY(XY+3)+(XY+4)+4(X+Y+1)-(X+Y+2)
x²-y²+5x+3y+4(x+y-2xy)(x+y-z)+(xy-1)²
(x+2y-3xy)-(-2x-y+xy),其中x+y=1/2,xy=-1/2
2x²y-3(2xy-xy)-xy
已知3/(x-y)=1/xy 求(-x-2xy+y)/ (2x+3xy-2y)
(x+y)(x-y)-(2xy+3y)平方平方是(2xy+3y)的
已知xy/x+y=1/2,则代数式3x-5xy+3y/-x+3xy-y=
x*x+xy=3,xy+y*y=2,则x*x+2xy+y*y=________?
