初二数学各位帮帮忙是否存在整数m（m≠0）使关于x的不等式的解集相同？
与x-2+m/m+9/m²m&#1781+3x/＞x/3＜x+1不要复制谢谢注意是m的&#178

1+3x/m&#178;m&3+m x-2+m/3;3＜x+1请问这个不等式的左边是（x-2+m）/&m+9/m&#178;)/3还是x-2+m/m&#178;9/＞x/m&#178;(3-m)(3+m)
x&m&#178;9-m&#178;
x(3-m)&(9-m&#178;
(3x-xm)/m&#178解
第二个式子两边的x一约掉就没了，得m&9，且x取遍所有数。第一个式子解得x&3-m^2(m的平方)，所以说m取负无穷时，x就大于负无穷了。要两个不等式关于x解集相同，则m&9即可！

2.设集合M=｛x|x=5n+2,n∈Z｝,N=｛y|y=5k-3,k∈Z｝,试求集合M与N的关系.3.已知集合A=｛x|x的平方-3x=0｝,B=｛y|y的平方+4(a-1)y+（a的平方-1=0｝求若B是A的自子集,求实数a的取值范围(要过程)
m^2-n^2=(m+n)(m-n) 而102=2*51=2*3*17 所以m+n=51,m-n=2或者m+n=34,m-n=2或者m+n=17,m-n=6解三个方程组,只有第二个方程组有正整数解m=18,n=16所以102=18^2-16^2所以102属于那个集合 5n+2=5(n+1)-3 因为n是整数,所以n和n+1表示的范围是一样的,都表示整数 所以M=N A={0,3} 情况一：当B是空集时,方程无解,所以判别式=16(a-1)^2-4(a^2-1)
1,求102的因数，是2，3和17。M的平方-N的平方，也就是M+N乘以M-N，也就是两个数的相乘，那么2X51，3X34，6X17都不满足，所以是不属于2，我忘记Z是不是整数集了，如果是整数集，那么M=N。因为如果是整数集，那么可以取K=N+1，那么5K-3=5（N+1）-3=N+23.a是空集.因为A是{3，0}，B是A的子集，有两种情况，一，B={3，0}，即y...

非常感谢帮助啊！！！
这个是你程序有BUG,在那个断言的地方有空指针或者空窗口句柄
你可以通过查看调用堆栈来找到对应到你代码的错误位置，然后设置断点调试0xBAADF00D

有啊！！！
哦，是我用错控件了，我用了List Box，对了，控件与变量关联不是可以直接在控件右键添加变量就行了吗？那个DDX是干吗的啊？？？？
您可以右键关联一个控件变量，然后观察对话框类的DoDataExChange函数中的变化就很清楚了Visual C&#43;&#43; enthusiast, like network programming and driver development. At present is being engaged in the WinCE/Windows Mobile platform embedded development.

您的m_ctrlList对象应该还没有关联CListCtrl窗口对象吧，您的对话框类的DoDataExChange函数中有类&#20284;DDX_Control(pDX, IDC_LIST1, m_ctrlList);这样的代码吗？Visual C&#43;&#43; enthusiast, like network programming and driver development. At present is being engaged in the WinCE/Windows Mobile platform embedded development.

可是我在DodataExChangeDDX_Control（pDX,IDC_LIST1,m_ctrlList)后，会出现另一个中断，在堆栈帧出现下面的框架缺失或不正确安装，没有为KernerBase.dll加载符号，msvrc90d.dll!_CrtDbgBreak()这是怎么回事啊？？？？

您的资源编辑器中的对话框模板上有拖放一个CListCtrl控件吗？Visual C&#43;&#43; enthusiast, like network programming and driver development. At present is being engaged in the WinCE/Windows Mobile platform embedded development.
