2\left(x^{2}-25\right)
Ffactora allan 2.
\left(x-5\right)\left(x+5\right)
Ystyriwch x^{2}-25. Ailysgrifennwch x^{2}-25 fel x^{2}-5^{2}. Gellir ffactorio’r gwahaniaeth rhwng sgwariau gan ddefnyddio’r rheol: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).
2\left(x-5\right)\left(x+5\right)
Ailysgrifennwch y mynegiad cyfan wedi'i ffactorio.
