3\left(x^{5}-16x^{3}\right)
Factor out 3.
x^{3}\left(x^{2}-16\right)
Consider x^{5}-16x^{3}. Factor out x^{3}.
\left(x-4\right)\left(x+4\right)
Consider x^{2}-16. Rewrite x^{2}-16 as x^{2}-4^{2}. The difference of squares can be factored using the rule: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).
3x^{3}\left(x-4\right)\left(x+4\right)
Rewrite the complete factored expression.
