\frac{4x^{2}-1}{36}
Ffactora allan \frac{1}{36}.
\left(2x-1\right)\left(2x+1\right)
Ystyriwch 4x^{2}-1. Ailysgrifennwch 4x^{2}-1 fel \left(2x\right)^{2}-1^{2}. Gellir ffactorio’r gwahaniaeth rhwng sgwariau gan ddefnyddio’r rheol: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).
\frac{\left(2x-1\right)\left(2x+1\right)}{36}
Ailysgrifennwch y mynegiad cyfan wedi'i ffactorio.
