$$ \LARGE \frac{\frac{1/x}{1}}{x^2-1} $$

anonymous · Answer

thats not even one of the choices.

helder_edwin · Answer

i am rewritting what u have in order for u to do the operations correctly!!!!!!
or u r just waiting for the answer??

anonymous · Answer

Oh okay. You can show me how to do it.

helder_edwin · Answer

first
$$ \large \frac{a}{1}=? $$

anonymous · Answer

a

helder_edwin · Answer

yes so in the numerator what do u get??

anonymous · Answer

a

helder_edwin · Answer

no in the problem u r supposed to solve

helder_edwin · Answer

my very first post

anonymous · Answer

oh sorry I would get x

helder_edwin · Answer

no

anonymous · Answer

thats what I'm screwing up on. I don't know if I'm suppose to do the reciprocal and multiply that by the numerator.

anonymous · Answer

?

helder_edwin · Answer

$$ \large \frac{1/x}{1}=? $$

helder_edwin · Answer

$$ \large \frac{a}{1}= $$
it is the same!!!

anonymous · Answer

thats not even the equation.
