若x-y=5,xy=6,求x^2-xy^2和x^2y+xy^2若x-y=5,xy=6,求x^2-xy^2和x^2y+xy^2若x-y=5,xy=6,求x^2-xy^2和x^2y+xy^2x=-1,y=
若x-y=5,xy=6,求x^2-xy^2和x^2y+xy^2
若x-y=5,xy=6,求x^2-xy^2和x^2y+xy^2
若x-y=5,xy=6,求x^2-xy^2和x^2y+xy^2
x = -1,y = -6或
x = 6,y = 1
代入式子得
x^2 - x y^2 = 37或30
x^2 y + x y^2 = -42或42
若x-y=5,xy=6,求x^2-xy^2和x^2y+xy^2
若x+y=5,xy=6,求x^2y+xy^2的值
若x+y-5xy=0,求(2x-3xy+2y)/(x+2xy+y)的值
诺x+y=6,xy=4 求(5x-4y-3xy)-(8x-y+2xy)
若xy=2（x+y),求 （3x-5xy+3y)÷(-x+3xy-y) 的值
1-2/x+y=xy,4y+6x=xy.求xy的解?
若正实数x,y满足2x+y+6=xy,求xy的最小值.
若正实数X,Y满足2X+Y+6=XY,求XY的最小值.
x+y=8,xy=-2,求(5xy+4x+7y)+(6x-3xy)-(4xy-3y)的值
已知x^2-xy=5,xy-y^2=-3求3(x^2-xy)-xy+y^2
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
已知xy^2=-2,求-xy（x^2y^5-xy^3-y)的值.
已知xy^2=-2 求-xy(x^2y^5-xy^3-y)
xy^2=-3,求-xy(x^2y^5-xy^3-y)
若x^2+xy+y=14,y^2+xy+x=28,求x+y
若2x²+xy+3y²=-5,求(9x²+2xy+6)-(xy+7x²-3y²-5)的值
x+y=6,xy=8,求5x+xy+5y/x-xy+y的值
若(y-x)/xy=3,求分式(2x+3xy-2y)/(x-2xy-y)的值
