HELP!! 
Simplify each and state the excluded values.

are there any type-o's?

anonymous · Answer

Yeah on the third one

freckles · Answer

$$m-\frac{8}{8}m-64 ? \ n-\frac{2}{10}n-20? \ n^2+18n+\frac{81}{n^2}+17n+72 ? \ 12x+\frac{24}{30}x+6?$$

this looks funny to me

freckles · Answer

I think you meant 
(m-8)/(8m-64)
(n-2)/(10n-20)
(n^2+18n+81)/(n^2+17n+72)
(12x+24)/(30x+6)

freckles · Answer

which has translation
$$\frac{m-8}{8m-64} \ \frac{n-2}{10n-20} \ \frac{n^2+18n+81}{n^2+17n+72} \ \frac{12x+24}{30x+6}$$

anyways to find the excluded values set all the bottoms of any fractions equal to zero and solve
