[x(x^2y^2-xy)-y(x^2-x^3y)]/3x^2y
[x(x^2y^2-xy)-y(x^2-x^3y)]/3x^2y
[x(x^2y^2-xy)-y(x^2-x^3y)]/3x^2y
[x(x^2y^2-xy)-y(x^2-x^3y)]/3x^2y
=(x^3y^2-x^2y-x^2y+x^3y^2)/3x^2y
=(2x^3y^2-2x^2y)/3x^2y
=2x^3y^2/3x^2y-2x^2y/3x^2y
=(2xy-2)/3
[x(x^2y^2-xy)-y(x^2-x^3y)]/(3x^2y)
={x[xy(xy-1)]-y[x²(1-xy)]}/(3x²y)
=[x²y(xy-1)-yx²(1-xy)]/(3x²y)
=[x²y(xy-1)+yx²(xy-1)]/(3x²y)
=[x²y(xy-1)+x²y(xy-1)]/(3x²y)
=[2x²y(xy-1)]/(3x²y)
=[2(xy-1)]/3
(-x-y)(x^2+xy+y^2)
化简x^-y^/x^-2xy+y^
2*(x-y)²(y-x)(xy)
（x^2+xy/x-y)/（xy/x-y)计算
