Program : To obtain solution of second order quadratic equation
#include <stdio.h>
#include <math.h>
int main() {
float a, b, c;
float desc, root1, root2;
printf("\nEnter the Values of a : ");
scanf("%f", &a);
printf("\nEnter the Values of b : ");
scanf("%f", &b);
printf("\nEnter the Values of c : ");
scanf("%f", &c);
desc = sqrt(b * b - 4 * a * c);
root1 = (-b + desc) / (2.0 * a);
root2 = (-b - desc) / (2.0 * a);
printf("\nFirst Root : %f", root1);
printf("\nSecond Root : %f", root2);
return (0);
}
Enter the Values of a : 1
Enter the Values of a : -5
Enter the Values of a : 6
First Root : 3.000000
Second Root : 2.000000
