\frac{-36x^{2}+1}{4}
Factor out \frac{1}{4}.
\left(1-6x\right)\left(1+6x\right)
Consider -36x^{2}+1. Rewrite -36x^{2}+1 as 1^{2}-\left(6x\right)^{2}. The difference of squares can be factored using the rule: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).
\left(-6x+1\right)\left(6x+1\right)
Reorder the terms.
\frac{\left(-6x+1\right)\left(6x+1\right)}{4}
Rewrite the complete factored expression.
