2\left(-ab^{2}+121a\right)
Factor out 2.
a\left(-b^{2}+121\right)
Consider -ab^{2}+121a. Factor out a.
\left(11-b\right)\left(11+b\right)
Consider -b^{2}+121. Rewrite -b^{2}+121 as 11^{2}-b^{2}. The difference of squares can be factored using the rule: p^{2}-q^{2}=\left(p-q\right)\left(p+q\right).
\left(-b+11\right)\left(b+11\right)
Reorder the terms.
2a\left(-b+11\right)\left(b+11\right)
Rewrite the complete factored expression.
