Answer 4

1) The domain of the expression is the value of variable that make the expression has meaning.
\(\dfrac{c^2-16c+18}{c-2}\) has meaning when the denominator \(\neq 0\)
That is \(c-2\neq 0\rightarrow c\neq 2\), hence domain is \(\mathbb R/\{2\}\)

Answer 5

2) they already have the same denominator, just combine the numerator
\[\frac{x-3x^2+1-(5x^2+6)}{2x-1}=\frac{x-8x^2-5}{2x-1}\]

Answer 6

This is the first and the last time I rescue you from deadline. Next time, don't wait until deadline to make question so that you can get something from making question. Remember, FREE ANSWER DOESN'T HELP.

Answer 7

where did you get 16c for number 1?

Answer 8

Just typo, since the numerator does nothing in finding domain, I don't really care on typing it.

Answer 9

got it, thanks.
