Make a Program About Quadratic Equation.Now We make C++ Program to Find All Roots of a Quadratic Equation.

C++ Program to Find All Roots of a Quadratic Equation

#include<iostream>
#include<math.h>
using namespace std;
int main()
{
float root1,root2,a,b,c,d,imaginaryPart,realPart;
cout<<"Quadratic Equation is ax^2+bx+c=0";
cout<<"\nEnter values of a,b and c:";
cin>>a>>b>>c;

d=(b*b)-(4*a*c);

if(d>0)
{
cout<<"\nTwo real and distinct roots";
root1=(-b+sqrt(d))/(2*a);
root2=(-b-sqrt(d))/(2*a);
cout<<"\nRoots are "<<root1<<" and "<<root2;
}
else if(d==0)
{
cout<<"\nTwo real and equal roots";
root1=root2=-b/(2*a);
cout<<"\nRoots are "<<root1<<" and "<<root2;
}
else{
cout<<"\nRoots are complex and imaginary";
realPart = -b/(2*a);
imaginaryPart = sqrt(-d)/(2*a);
cout<<"\nRoots are "<<realPart<<"+"<<imaginaryPart<<"i and
 "<<realPart<<"-"<<imaginaryPart<<"i";
}

return 0;
}
