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