int main(){
float a,b,c;
float d,root1,root2;

printf("Enter quadratic equation in the format ax^2+bx+c: ");
scanf("%fx^2%fx%f",&a,&b,&c);

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

if(d < 0){
printf("Roots are complex number.
");

return 0;
}

root1 = ( -b + sqrt(d)) / (2* a);
root2 = ( -b - sqrt(d)) / (2* a);
printf("Roots of quadratic equation are: %.3f , %.3f",root1,root2);

return 0;
}
