EXPERIMENT 3

PRACTICAL : 3.1

Aim: FIND ROOTS OF QUADRATIC EQNS

code:

#include<stdio.h>
#include<math.h> /* mthis includes math functions like pow*/
void main(){
    float a,b,c,root1,root2,D,real,img;
    printf("Enter value of 'a': ");
    scanf("%f",&a);
    printf("Enter value of 'b': ");
    scanf("%f",&b);
    printf("Enter value of 'c': ");
    scanf("%f",&c);
    
    D=b*b-4*a*c;
    printf("\nDescriminent= %f",D);
    
     if (D==0){
         root1=root2=-b/(2*a);
         printf("\nRoots are equal: %f",root1);
     }
     else if(D>0){
         root1=-b+sqrt(D)/(2*a);
         root2=-b-sqrt(D)/(2*a);
         printf("\nDifferent Roots fount! They are: \n 1. %f \n 2. %f",root1,root2);
     }
     else real=-b/(2*a);
          img=sqrt(-D)/(2*a);
          printf("\nComplex numbers Fount; \n 1.Root 1: %f+%fi \n 2.Root 2: %f-%fi",real,img,real,img);
          
    printf("\n\n A Program by SUKH");
