9\left(9-x^{2}\right)
Ffactora allan 9.
\left(3-x\right)\left(3+x\right)
Ystyriwch 9-x^{2}. Ailysgrifennwch 9-x^{2} fel 3^{2}-x^{2}. Gellir ffactorio’r gwahaniaeth rhwng sgwariau gan ddefnyddio’r rheol: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).
\left(-x+3\right)\left(x+3\right)
Aildrefnu'r termau.
9\left(-x+3\right)\left(x+3\right)
Ailysgrifennwch y mynegiad cyfan wedi'i ffactorio.
