Question

HELP!!
Simplify each and state the excluded values.
M-8/8m-64, n-2/10n-20, n^2+18+81/n^2+17n+72, 12x+24/30x+6

Answer 1

***n^2+18n+81

Answer 2

are there any type-o's?

Answer 3

Yeah on the third one

Answer 4

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

Answer 5

this looks funny to me

Answer 6

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

Answer 7

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

Answer 8

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