〔5xy^2(x^2-3xy)-(-3x^2y^3)〕/2x^2y^2
=(5x³y² - 15x²y³+3x²y³)/(2x^2y^2)
=(5x³y² - 12x²y³)/(2x^2y^2)
=(5xy-12y)/2
=(5xy/2) - 6y

(x-2xy)*(-xy+2y*y)-(3x*x-2xy)(x-9xy+6y*y) x^3y(-4y)^2+(-7xy)^2*(-xy)-5xy^3*(-3x)^2 计算3xy[2xy-x(y-2)+x-1] 计算：3xy[2xy-x（y-2）+x] （-3x^y+2xy)-( )=4x^+xy x^2-xy-6y^2+3xy+y+2 若x+y-5xy=0,求(2x-3xy+2y)/(x+2xy+y)的值已知xy/x+y=3,求代数式2x-5xy+2y/x-3xy+y 已知xy/x+y=2,求代数式3x-5xy+3y/-x+2xy-y的值已知x+y分之xy=2,那么3x-5xy+3y分之3xy-x-y= 已知X+Y分之XY=2,求-X+3XY-Y分之3X+5XY+3Y 已知xy/x+y=1/2,则代数式3x-5xy+3y/-x+3xy-y=
