w^{2}\left(w-5\right)-36\left(w-5\right)
Do the grouping w^{3}-5w^{2}-36w+180=\left(w^{3}-5w^{2}\right)+\left(-36w+180\right), and factor out w^{2} in the first and -36 in the second group.
\left(w-5\right)\left(w^{2}-36\right)
Factor out common term w-5 by using distributive property.
\left(w-6\right)\left(w+6\right)
Consider w^{2}-36. Rewrite w^{2}-36 as w^{2}-6^{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-6\right)\left(w-5\right)\left(w+6\right)
Rewrite the complete factored expression.
