this is what i did #include <iostream> #include <cmath> using namespace std; int main() { int a, b , c float x1; float x2; cout<< "Enter the a" << endl; cin >> a; cout << "Enter b" << endl; cin >> b; cout << "Enter c" << endl; cin >> c; cout << "Your a, b and c is " << a << b << c << "Respectively"<< endl; x1 = (b*b) - sqrt( (b*b) - (2*a*c) / (2*a) x2 = (b*b) + sqrt( (b*b) - (2*a*c) / (2*a) cout << "The first root of the quadratic equation is " << x1 << endl; cout << "The second root of the quadratic equation is "<< x2 << endl; return 0; }

@$Vengat you can use this to find root of any form of equation. But only one root. https://code.sololearn.com/cUSS7rcnePZ1/?ref=app
