\frac{4x^{2}-1}{36}
Factor out \frac{1}{36}.
\left(2x-1\right)\left(2x+1\right)
Consider 4x^{2}-1. Rewrite 4x^{2}-1 as \left(2x\right)^{2}-1^{2}. The difference of squares can be factored using the rule: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).
\frac{\left(2x-1\right)\left(2x+1\right)}{36}
Rewrite the complete factored expression.
