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