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.
