A_{8}^{2}\left(A_{8}^{2}-4\right)
Factor out A_{8}^{2}.
\left(A_{8}-2\right)\left(A_{8}+2\right)
Consider A_{8}^{2}-4. Rewrite A_{8}^{2}-4 as A_{8}^{2}-2^{2}. The difference of squares can be factored using the rule: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).
A_{8}^{2}\left(A_{8}-2\right)\left(A_{8}+2\right)
Rewrite the complete factored expression.
