x\left(121-x^{2}\right)
Ffactora allan x.
\left(11-x\right)\left(11+x\right)
Ystyriwch 121-x^{2}. Ailysgrifennwch 121-x^{2} fel 11^{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+11\right)\left(x+11\right)
Aildrefnu'r termau.
x\left(-x+11\right)\left(x+11\right)
Ailysgrifennwch y mynegiad cyfan wedi'i ffactorio.
