Question

Help??
Everyone keeps telling me the answer is the following I even got this answer:

7•(a-7)/(a+8)•(a-8)

But that isn’t a answer choose that I can click??

simplify the sum 7/a+8 + 7/a^2-64

Answer 1

7 / a+8 + 7 / a^2 - 64

The LCm is a^2 - 64

=  7(a - 8) + 7  /  a^2-64

=  (7a - 49) / (a^2-64)

= 7(a-7) / [(a+8)(a-8)]  answer
