so how would i implement the outputs and conditions like i said above into my code below???


changed my code:

Code:
// Quadratic Equation.cpp : main project file.
#include <cmath>  // defines the sqrt() function
#include <iostream>
using namespace std;

int main()
{ // implements the quadratic formula
  float a, b, c;
 
  cout << "Enter the coefficients of a quadratic equation:" << endl;
  cout << "a: ";
  cin >> a;
  cout << "b: ";
  cin >> b;
  cout << "c: ";
  cin >> c;

  cout << "The roots of " << a << "*x*x + " << b
       << "*x + " << c << " = 0" << endl;
  
  float d = b*b - 4*a*c;  // discriminant
  float sqrtd = sqrt(d);
  float x1 = (-b + sqrtd)/(2*a);
  float x2 = (-b - sqrtd)/(2*a);
  
  cout << "are:" << endl;
  cout << "x1 = " << x1 << endl;
  cout << "x2 = " << x2 << endl;

}
