x^n*y*(-x^2y^m)
(x+y)(m+n)2-(x+y)(m+n)2
m(x-y)^n+n(y-x)^2n因式分解
若[-3(x+y)^m*(x-y)^2n]^2*[-(x+y)^2]=-a(x+y)^10*(x-y)^12-n,求m,n的值
x+y=m,x-y=n,那么2x-3y等于
x+y=m,x-y=n,那么2x-3y等于多少
设X>0,y>0,M=(X+Y)/(2+X+Y),N=(X/2+X)+(Y/2+Y),则M,N的大小关系?
已知集合M={(x,y)|y=-x^2+2x},N={(x,y)|y=2x^2-4x},则M∩N=?
提公因式m^2(x-y)+n^2(y-x)
2m(x+y)+n(x+y) 因式分解快
2m(x+y)+n(x+y) 因式分解
已知M=(x,y)|y>=x2 N=(x,y)|x2+(y-a)2
假设集合U={(x,y)|x∈R,y∈R },A={(x,y)|2x-y+m>0},B={(x,y)|x+y-n
因式分解:m^2(x-y)+n^2(y-x)m^2(x-y)+n^2(y-x) .如题.
集合N={(x,y)|(x-1)^2}+(y-1)^20},M={(x,y)|x^2+y^2
已知集合M={(x,y)|x^2+y^2=0},N={(x,y)||x|+|y|
已知M={(x,y)|y=-x^2+mx-1},N={(x,y)|y=-x+3,0
若不等式组x>m,x=2,y+n
