Let f(x) = (3x^2 - 10x - 25)/(x - 3) and g(x) = (3x^2 - 10x - 25)/(3x^2 + 11x + 7). Find the sum of all real numbers that are not in the domain of f(g(x)).
The believe that the only value not in the domain is 3, which makes the denominator
of f(x) = 0.
I believe that the denominator of g(x) will never become 0.
