My issue

right code

My code

#include <stdio.h>
#include <math.h> 
int main() {
	// your code goes here
int a , b , c;
double discriminant,root1,root2,realpart,imagpart;
scanf("%d %d %d",&a,&b,&c);
discriminant=b*b-4*a*c;
if(discriminant>0){
    root1=(-b+sqrt(discriminant))/(2*a);
    root2=(-b-sqrt(discriminant))/(2*a);
    if(root1>root2){
        printf("%.2lf\n%.2lf\n",root1,root2);
    } else{
        printf("%.2lf\n%.2lf\n",root2,root1);
    }
} else if(discriminant==0){
    root1=-b/(2.0*a);
    printf("%.2lf\n",root1);
}
else{
    realpart=-b/(2.0*a);
    imagpart=sqrt(-discriminant)/(2*a);
    printf("%.2lf-%.2lfi",realpart,imagpart);
    printf("%.2lf-%.2lfi",realpart,imagpart);
}
return 0;
}
