   cin >> a;
   cout<<"input your's= ";
   cin >> b;
   cout<<"input your's= ";
   cin >> c;
   disk =b*b-4*a*c;
   if (disk>0)
   {
      x1 =-b/2*a;
      x2 =x1;
   }
   else
   {
      if (disk==0)
      {
         x1 =(-b+sqrt(disk))/2*a;
         x2 =(-b-sqrt(disk))/2*a;
      }
      else
      {
         cout << "Akar Imajinatier:" << endl;      }
