#define eps 0.0000001
using namespace std;


double L,K,T1,T2,H;






int main()
{
 
 int ts,p,i,fnd;
 double l,u,t,l1,u1,t1,rt,rs;
 
 while(cin>>ts)
 {
  for(p=1;p<=ts;p++)
  {
   cin>>L>>K>>T1>>T2>>H;
   
   l=0,u=10000;
   l1=0,u1=T1;
   
   if(H<L&&K<(L/T1)) printf("%.6lf %.6lf\n",H,H);
   else
   {
       fnd=0;
       for(i=0;i<5000;i++)
   {
   t1=(l1+u1)/2;
   rt=L/t1;
   rs=T1+T2-t1;
   if(fabs(L+rt*(T1-t1)-rs*K-H)<eps) {fnd=1;break;}
   else if(L+rt*(T1-t1)-rs*K>H) l1=t1;
   else u1=t1;
   
   
   
  
   }
    
  
  
 if(fnd)   printf("%.6lf %.6lf\n",H,L+rt*(T1-t1));

I am wondering if anyone can provide a hint about how to set up the problem as a quadratic equation.
