Solve Second Order Quadratic Equation : C Program

Computer Science » C Program » Solve Second Order Quadratic Equation 

Program :

#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);
}

Output :

Enter the Values of a : 1
Enter the Values of b : -5
Enter the Values of c : 6
First Root : 3.000000
Second Root : 2.000000
