看了一下题,(x^3+xy^2+1)/(x^3+xy^2-x^2y-y^3)×(x^2y-xy^2)/(x^3+xy^2-x^2y-y^3),两个分母居然也是一样的,而且x^2y+y^2这样的次数,我总觉得题目是不对的...
仔细看 下题目，第一个加法后的因式的次数不相等~~x^2y+y^2确定没出错？
3xy(x^2-xy^2+xy)-xy^2(2x^2-xy+2x)
1-(3xy-x)+【-2(2x+3xy)】
计算3xy[2xy-x(y-2)+x-1]
【x(xy-xy)-y(x-xy)】÷3xy
因式分解X^3-2xy+xy^2
2x²y-3(2xy-xy)-xy
xy(xy+1)+xy+3-2(x+y+1/2)-(x+y-1)^2因式分解
(-1/3xy)^2•[xy(2x-y)-2x(xy-y^2)]
(-3分之1xy)的平方×[xy(2x-y)-2x(xy-y的平方)]
XY(XY+3)+(XY+4)+4(X+Y+1)-(X+Y+2)
已知（x+1）*（x+1）=-Iy-1I,求2（xy-（5xy）*（5xy））-3（（xy）*（xy）-xy）
(-xy^-1)^2*(-xy^-2)^-3/(-x^2y^3)
( )-(x^2+3xy)=-xy-1/3y^2
y^3+xy^2+2xy+x^2-1 因式分解
5x^2y/-1/2xy*3xy^2
5xy^2-{2x^y-[3xy^2-（xy^2-2x^2y）]/（-1/2xy）}
化简!1、（x^2-xy）+xy+y^2 2、3（x^2-xy）-xy+y^2
化简:xy分之3x^2+2xy-xy分之2x^2-xy=
