Answer 1

To simplify the sum, we need to combine like terms and simplify any fractions.

Starting with the first expression:
\(7a - \frac{49}{(a - 8)(a + 8)}\)

For the second expression:
\(\frac{14}{a^2 - 56}\)

For the third expression:
\(\frac{14}{(a - 8)(a + 8)}\)

There is no "sum" indicated or given in the question. Therefore, it is unclear what exactly needs to be simplified. Please provide more information or clarify the question.
