\frac{\left(343n-175\right)\left(n^{2}-7n+10\right)}{\left(7n^{2}-19n+10\right)\left(35n^{2}+4n-15\right)}
Dividiu \frac{343n-175}{7n^{2}-19n+10} per \frac{35n^{2}+4n-15}{n^{2}-7n+10} multiplicant \frac{343n-175}{7n^{2}-19n+10} pel recíproc de \frac{35n^{2}+4n-15}{n^{2}-7n+10}.
\frac{7\left(n-5\right)\left(n-2\right)\left(49n-25\right)}{\left(n-2\right)\left(5n-3\right)\left(7n-5\right)\left(7n+5\right)}
