b\left(64b^{2}-81\right)
Factor out b.
\left(8b-9\right)\left(8b+9\right)
Consider 64b^{2}-81. Rewrite 64b^{2}-81 as \left(8b\right)^{2}-9^{2}. The difference of squares can be factored using the rule: p^{2}-q^{2}=\left(p-q\right)\left(p+q\right).
b\left(8b-9\right)\left(8b+9\right)
Rewrite the complete factored expression.
