Thread: Would anyone be kind enough to help me with my math homework?

1. Would anyone be kind enough to help me with my math homework?

Would anyone care to explain steps to these rational equations. (Please include the answers)

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

2. You state that these are equations, but I don't see equal signs on either pic. Or did you need to simplify the rational expressions?

3. 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.
$\displaystyle x+3/x^2-9 - 5$
$\displaystyle x\neq 3, x\neq -3$
$\displaystyle (- \infty, -3) \bigcup (-3,3) \bigcup (3, \infty)$

$\displaystyle 6/x-3$
$\displaystyle x\neq 3$
$\displaystyle (- \infty, 3) \bigcup (3, \infty)$
