Ffactora allan 25.
\left(1-2f\right)\left(1+2f\right)
Ystyriwch 1-4f^{2}. Ailysgrifennwch 1-4f^{2} fel 1^{2}-\left(2f\right)^{2}. Gellir ffactorio’r gwahaniaeth rhwng sgwariau gan ddefnyddio’r rheol: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).
\left(-2f+1\right)\left(2f+1\right)
Aildrefnu'r termau.
25\left(-2f+1\right)\left(2f+1\right)
Ailysgrifennwch y mynegiad cyfan wedi'i ffactorio.
