\( \large\frac{\left(4r^2-32r-80\right)\cdot\left(r-6\right)}{\left(r^2-12r+36\right)\cdot\left(20-2r\right)} \)
\( \large=\frac{-2\left(r-2\right)}{\left(r-6\right)}=-\frac{2r-4}{r-6} \)
\( \large=\frac{-2\left(r+2\right)}{\left(r-6\right)}=-\frac{2r+4}{r-6} \)
\( \large=\frac{2\left(r+2\right)}{\left(r-6\right)}=\frac{2r+4}{r-6} \)
\( \large=\frac{-2\left(r+2\right)}{\left(r+6\right)}=-\frac{2r+4}{r+6} \)
