Using long division, we have


[tex]a^{2}-1 ____________________ a^{n}+8 | a^{2n} -a^{n}-6 -(a^{2n}+8a^{2}) -a^{n}-8a^{2}-6 -(-a^{n}+8) -8a^{2}-14[/tex]

The parenthesis are the result of what we multiply (a^n+8) by (we multiply it by the top expression - we start with a^2 then -1), and what's not is the result of adding the parenthesis to the expression about that.

Our final result is (a^n+8)*(a^2-1)-8a^2-14
