2\left(49n^{2}-100\right)
Factor out 2.
\left(7n-10\right)\left(7n+10\right)
Consider 49n^{2}-100. Rewrite 49n^{2}-100 as \left(7n\right)^{2}-10^{2}. The difference of squares can be factored using the rule: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).
2\left(7n-10\right)\left(7n+10\right)
Rewrite the complete factored expression.
