\left(x-16\right)\left(x+16\right)
Ystyriwch x^{2}-256. Ailysgrifennwch x^{2}-256 fel x^{2}-16^{2}. Gellir ffactorio’r gwahaniaeth rhwng sgwariau gan ddefnyddio’r rheol: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).
3\left(x-16\right)\left(x+16\right)
Ailysgrifennwch y mynegiad cyfan wedi'i ffactorio.
