${x}^{10} - 9$

#### Explanation:

$\left({x}^{5} + 3\right) \left({x}^{5} - 3\right)$
First multiply ${x}^{5}$ by ${x}^{5}$ to get ${x}^{10}$
Second, multiply ${x}^{5}$ by $- 3$ to get $- 3 \left({x}^{5}\right)$
Third,multiply ${x}^{5}$ by $3$ to get $3 \left({x}^{5}\right)$
Last, multiply $3$ by $- 3$ to get $- 9$
Add them all together to get ${x}^{10} - 9$
