Explanation / Answer

#include <iostream>
#include <cmath>
using namespace std;

int main()
{
   float a,b,c,disc,r1,r2;
   a= 2;
   b = 4;
   c = 2;
  
   disc = b*b - 4*a*c;
   r1 = (-b + sqrt(disc))/(2*a);
   r2 = (-b - sqrt(disc))/(2*a);
  
  
   if(disc >0)
   {
   r1 = (-b + sqrt(disc))/(2*a);
   r2 = (-b - sqrt(disc))/(2*a);
   cout<<" The roots of the equation are :";
   cout<<" r1 " <<r1<<endl;
   cout<<" r2 " <<r2<<endl;
   }
   else if(disc == 0)
   {
       r1 = -b /(2*a);
       cout<<" The double root is "<<r1;
  
   }
  
   return 0;
}
