已知xx+y=5,xy=-3,则x^2y+xy^2=
已知xx+y=5,xy=-3,则x^2y+xy^2=
已知xx+y=5,xy=-3,则x^2y+xy^2=
x+y=5,xy=-3,则x^2y+xy^2=xy(x+y)=-3*5=-15
x+y=5
xy=-3
所以原式=xy(x+y)
=-3*5
=-15
已知xx+y=5,xy=-3,则x^2y+xy^2=
已知x(x-1)-(xx-y)=-3求xx+yy-2xy
已知x（x+1)-(xx+y)=3,求(xx+yy)/2-xy的值
已知2x=3y,求xy/xx+yy-yy/xx-yy的值
x,+y=5 xy=3 求xx+yy
x-y/x+y=2,则xx+2xy+yy/4xy=?
已知xy/x+y=1/2,则代数式3x-5xy+3y/-x+3xy-y=
已知X,Y为正整数,并且XY+X+Y=23,X^2Y+XY^2=120,求xx+yy今天5点之前,
已知xy/x+y=2,则代数式3x-5y+8y/-x+3xy-y的值
x(x+1)-(xx+y)=-3,求(xx+yy)/2-xy的值
已知x+y=-5,xy=3,则xx+yy=( ) A.25 B.-25 C.19 D.-19
已知x+y=5,xy=-3,则x^2y+xy^2,
已知A=2XX+3XY-1,B=-XX+XY-1,且3A+6B的值与X无关,求Y值
已知2/X-1/Y=3,则(X-2Y-XY)/(5XY+6Y-3X)=?
已知1/x=3+1/y,则(2x-5xy-2y)/(y+3xy-x)=_______.
已知2/x-1/y=3,则(2y-x+4xy)/(3x-6y-5xy)=?
已知1/x-1/y=-3,则x+5xy-y/3x-2xy-3y=
已知x-y=-3,xy=2则3x-5y-(x-3y-4xy)是多少
