已知M-(2x^2-3xy+xy^2)(-xy)=(2x^2y+xy^2)(x-2y),求多项式M已知M-(2x^2-3xy+xy^2)(-xy)=(2x^2y+xy^2)(x-2y),求多项式M已知
已知M-(2x^2-3xy+xy^2)(-xy)=(2x^2 y+xy^2)(x-2y),求多项式M
已知M-(2x^2-3xy+xy^2)(-xy)=(2x^2 y+xy^2)(x-2y),求多项式M
已知M-(2x^2-3xy+xy^2)(-xy)=(2x^2 y+xy^2)(x-2y),求多项式M
M=(2x^2 y+xy^2)(x-2y)-(2x^2-3xy+xy^2)(-xy)
很简单啊.
这明摆着是“待定系数”嘛
已知M-(2x^2-3xy+xy^2)(-xy)=(2x^2 y+xy^2)(x-2y),求多项式M
已知M-(2x的平方-3xy+xy的平方)(-xy)=(2x的平方y+xy的平方)(x-2y)
(-3xy+2xy)-(4xy+xy)
3xy(x^2-xy^2+xy)-xy^2(2x^2-xy+2x)
由已知x+y=-2,xy=3那么2(x+xy)-[(xy-3y)-x]-(-xy)等于多少?
已知x:y=3:2,求(x²+3xy)/(xy+2xy)
已知(x+1)*(x+1)=-Iy-1I,求2(xy-(5xy)*(5xy))-3((xy)*(xy)-xy)
(3x^ny-2xy^2+xy^m+1)*(-2xy)
已知x^2-xy=5,xy-y^2=-3求3(x^2-xy)-xy+y^2
已知多项式2xy²-M课分解为2xy(x-3y-1),则M是
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)
已知xy^2=-2xy(x^2y^5-xy^3-y)
已知xy为正整数,3xy=2x+3y+5.求xy=?
已知 x+y=4,xy=2,求2xy+4xy+2xy
已知(x+1)²+|y-1|=0,求2(xy-5xy²)-(3xy²-xy)得值
2x²y-3(2xy-xy)-xy
因式分解X^3-2xy+xy^2
