Answers
The c program that stores the values -2, 3 and 5 in the variables a, b and c and displays the possible roots on separate lines is constructed throughout the answer.
What is the c program that models the given situation?The first step to the problem is storing the values -2, 3 and 5 in the variables a, b and c, done as follows:
int main(){
int a = -2;
int b = 3;
int c = 5;
Then we declare the roots, which could be decimal, as double.
double root1;
double root2;
Then we calculate the roots, as follows: (due to the sqrt function, library math.h has to be included, with command #include <math.h> before the main).
root1 = (-b - sqrt(b*b - 4*a*c))/(2*a);
root2 = (-b + sqrt(b*b - 4*a*c))/(2*a);
Then the values are printed as follows:
printf("Root 1: %lf\n", root1);
printf("Root 2: %lf", root2);
The \n command guarantees that they are printed on different lines.
At the end, we close the main, as follows:
return 1;

Answers
An isomorphism from a structure to itself is known as an automorphism. As a result, isomorphic structures can be recognized and cannot be discriminated solely based on their structure.
An isomorphism in mathematics is a structure-preserving mapping that allows for the reversal of two structures of the same kind. If there is an isomorphism between any two mathematical structures, they are said to be isomorphic. The Greek words isos, which means "equal," and morphe, which means "form" or "shape," are the roots of the word "isomorphism."
Because two identical objects areomorphic, there is interest in them due to their shared characteristics (excluding further information such as additional structure or names of objects). As a result, isomorphic structures can be recognized and cannot be discriminated solely based on their structure. According to mathematical language, two objects are equal up to an isomorphism.
