x\left(121-x^{2}\right)
Factor out x.
\left(11-x\right)\left(11+x\right)
Consider 121-x^{2}. Rewrite 121-x^{2} as 11^{2}-x^{2}. The difference of squares can be factored using the rule: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).
\left(-x+11\right)\left(x+11\right)
Reorder the terms.
x\left(-x+11\right)\left(x+11\right)
Rewrite the complete factored expression.
