$$((221 { p }^{ 2 } { q }^{ 2 } +13p { q }^{ 2 } +17p { q }^{ 2 } )(- \frac{ 1 }{ 663pq } )$$
$-\frac{pq}{3}-\frac{10q}{221}$
$$\left(221p^{2}q^{2}+30pq^{2}\right)\left(-\frac{1}{663pq}\right)$$
$$\frac{-\left(221p^{2}q^{2}+30pq^{2}\right)}{663pq}$$
$$\frac{-p\left(221p+30\right)q^{2}}{663pq}$$
$$\frac{-q\left(221p+30\right)}{663}$$
$$\frac{-221pq-30q}{663}$$
