Ffactora allan 2.
a\left(64m^{2}-121n^{2}\right)
Ystyriwch 64am^{2}-121an^{2}. Ffactora allan a.
\left(8m-11n\right)\left(8m+11n\right)
Ystyriwch 64m^{2}-121n^{2}. Ailysgrifennwch 64m^{2}-121n^{2} fel \left(8m\right)^{2}-\left(11n\right)^{2}. Gellir ffactorio’r gwahaniaeth rhwng sgwariau gan ddefnyddio’r rheol: p^{2}-q^{2}=\left(p-q\right)\left(p+q\right).
2a\left(8m-11n\right)\left(8m+11n\right)
Ailysgrifennwch y mynegiad cyfan wedi'i ffactorio.
