I would really like to know how to do these. I know it is alot of steps.

I'm pretty sure it's just finding the domain.
1.
$\displaystyle 10/x+2$
$\displaystyle x\neq -2$
$\displaystyle ( -\infty, -2) \bigcup (-2, \infty)$
$\displaystyle 9/x^2-4$
$\displaystyle x\neq 2, x\neq -2$
$\displaystyle (- \infty, -2) \bigcup (-2,2) \bigcup (2, \infty)$
2.
$\displaystyle x+3/x^2-9 - 5$
$\displaystyle x\neq 3, x\neq -3$
$\displaystyle (- \infty, -3) \bigcup (-3,3) \bigcup (3, \infty)$
$\displaystyle 6/x-3$
$\displaystyle x\neq 3$
$\displaystyle (- \infty, 3) \bigcup (3, \infty)$
