#include<iostream> 
using namespace std;
int main(){
int a,b,c,det,x1,x2;
while(cin>>a>>b>>c)
 {
 det=b*b-4*a*c;
if(det>0)
cout<<"Two different roots x1="<<-b+pow(det,0.5)/(2*a)<<","<<"x2="<<-b-pow(det,0.5)/(2*a)<<endl;
else if(det==0)
cout<<"Two same roots x="<<-b/(2*a)<<endl;
else
cout<<"No real root"<<endl;
}
return 0;
}
恩~~感覺是pow的問題
