# Finding roots of equations in C Language

``````#include <math.h>
#include <stdio.h>
int main() {
float a, b, c, discriminant, root1, root2, realPart, imagPart;
printf("Enter coefficients a: ");
scanf("%f", &a);
printf("Enter coefficients b: ");
scanf("%f", &b);
printf("Enter coefficients c: ");
scanf("%f", &c);

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

// condition for real and different roots
if (discriminant > 0) {
root1 = (-b + sqrt(discriminant)) / (2 * a);
root2 = (-b - sqrt(discriminant)) / (2 * a);
printf("root1 = %f and root2 = %f", root1, root2);
}

// condition for real and equal roots
else if (discriminant == 0) {
root1 = root2 = -b / (2 * a);
printf("root1 = root2 = %f;", root1);
}

// if roots are not real
else {
realPart = -b / (2 * a);
imagPart = sqrt(-discriminant) / (2 * a);
printf("roots are not real");
}

return 0;
}

#### Output:

```Enter coefficients a: 2
Enter coefficients b: 5
Enter coefficients c: 3
root1 = -1.000000 and root2 = -1.500000
