Write a C program to Finding all the roots of a quadratic equation

Program:-     

#include <stdio.h>
#include <math.h>

int main()
{
double a, b, c, discriminant, root1, root2, realPart, imaginaryPart;

printf("Enter coefficients a, b and c: ");
scanf(“%lf %lf %lf”,&a, &b, &c);

discriminant = b*b-4*a*c;

// condition for real and different roots
if (discriminant > 0)
{
// sqrt() function returns square root
root1 = (-b+sqrt(discriminant))/(2*a);
root2 = (-b-sqrt(discriminant))/(2*a);

printf("root1 = %.2lf and root2 = %.2lf",root1 , root2);
}

//condition for real and equal roots
else if (discriminant == 0)
{
root1 = root2 = -b/(2*a);

printf(“root1 = root2 = %.2lf;”, root1);
}

// if roots are not real
else
{
realPart = -b/(2*a);
imaginaryPart = sqrt(-discriminant)/(2*a);
printf("root1 = %.2lf+%.2lfi and root2 = %.2f-%.2fi", realPart, imaginaryPart, realPart, imaginaryPart);
}

return 0;
}

Output:-
