#include <iostream>

using namespace std;

int main()
{

double a,b,c; // you document
double r1,r2,disc;
// compute discriminant
// if disc > 0 print two real roots
// if disc < 0 print two imaginary roots
// if disc = 0 print one real root
cout<<"enter the three coefficients of the quadratic equation a,b,c\n";
cout<<"be sure that the discriminant is greater than 0\n";
cin>>a>>b>>c; //input coef of quad eqtn
cout<<a<<" "<<b<<" "<<c<<endl; // echo back to user
disc=b*b - 4*a*c; //compute disc
cout<<disc<<endl; // print disc
