Hello there.
First, assume the numbers
such that they satisties both affirmations:
- The sum of the squares of two numbers is
. - The product of the two numbers is
.
With these informations, we can set the following equations:

Multiply both sides of the second equation by a factor of
:

Make 

We can rewrite the expression on the left hand side using the binomial expansion in reverse:
, such that:

The square of a number is equal to
if and only if such number is equal to
, thus:

Substituting that information from
in
, we get:

Calculate the square root on both sides of the equation:

Once again with the information in
, we have that:

The set of solutions of that satisfies both affirmations is:

This is the set we were looking for.
Carlos would have to get 92
Plug in the numbers and add them to what he got on his original test and that would be (92=answer)
