\frac{1-256z^{2}}{16}
Factor out \frac{1}{16}.
\left(1-16z\right)\left(1+16z\right)
Consider 1-256z^{2}. Rewrite 1-256z^{2} as 1^{2}-\left(16z\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(-16z+1\right)\left(16z+1\right)
Reorder the terms.
\frac{\left(-16z+1\right)\left(16z+1\right)}{16}
Rewrite the complete factored expression.
