Please help! Kind of confused over the process of this question.

OpenStudy (jojokiw3):

\[3a - \frac{ 3 }{ a - \frac{ 3 }{ a } }\]

OpenStudy (stefrheart):

Wow i think i have a way to solve it but i want to be clear thats all right? its not multiple choice or anything?

OpenStudy (jojokiw3):

Yeah. It's not multiple choice.

OpenStudy (jojokiw3):

Just simply simplify.

OpenStudy (stefrheart):

okay first you need to simplify the bottom

OpenStudy (jojokiw3):

@stefrheart So is the bottom \[\frac{ a^2 - 3}{ a }\]?

OpenStudy (stefrheart):

woah..

OpenStudy (aum):

\[\large 3a - \frac{ 3 }{ a - \frac{ 3 }{ a } } = 3a - \frac{ 3 }{ \frac{ a^2-3 }{ a } } = 3a - \frac{ 3a }{ a^2-3} = \frac{3a^3-9a-3a}{a^2-3} = \\ \large \frac{3a^3-12a}{a^2-3} = \frac{3a(a^2-4)}{a^2-3} = \frac{3a(a-2)(a+2)}{a^2-3} \\ \large \]

OpenStudy (stefrheart):

yeah thats what i got @aum not what you got @jojokiw3

OpenStudy (jojokiw3):

Oh okay. thanks for the help!.

OpenStudy (aum):
