设集合A={(x,y)|y=x^2+mx+2},B={(x,y)|x-y+1=0,x
设集合A={x|x^2+mx+1=0,x∈R},B=y|y
设集合A={(x,y)|y>=|x-2|,x>=0},B={(x,y)|y
设集合A={(x,y)|y≥|x-2|,x>=0},B ={(x,y)|y
集合A={(x,y)|x^2+mx-y+2=0},集合B={(x,y)|x-y+1=0,且0
已知集合A={(x,y)|x*x+mx-y+2=0},B={(x,y)|x-y+1=o,0
已知集合A={(x,y)|x^2+mx+2=y},B={(x,y)|x-y+1=0,0
高二数学题难死了集合A={(x,y)丨y=-x^2+mx-1},B={(x,y)丨y=3-x,0
1.设全集U={X不好意思打错了~集合A={(x,y)|x2+mx-y+2=0},集合B={(x,y)|x-y+1=0,
设集合A={x,y,x+y},B={0,x平方,2x+y},且A=B,求实数x,y的值
集合A={(x,y)|x^2+mx-y+2=0},集合{(x,y)|x-y+1=0,且0
已知集合A={(x,y) | x^2+mx-y+2=0} ,B={(x,y) | x-y .,求实数m的取值笵围.
设集合A={(X,Y)/Y=X^2+AX+2} B={(X,Y)/Y=X+1,0
