Question

Simplify. ({1/36}- {1/x^2}) /  ({1/6}+{1/x})

anonymous · Answer

(x+18)(x-12)/36x(x+6) 
This is the answer if I have the formula absolutely correct.

anonymous · Answer

If I have this wrong, I do not see where, but it is possible. I hope I helped :)

one minute. I dont think it is completely simplified.

grant330sims · Answer

and if it is, it's not one of the answers on this quiz...

anonymous · Answer

Hmm.... Hold on I will re check it.

anonymous · Answer

6x^2-1/x
Here. You were right, It was an unfinished simplification. My bad :)

grant330sims · Answer

thats not it either..

anonymous · Answer

Well then the format must be wrong for this roblem becuase I'm pretty proficient with these things

anonymous · Answer

({1/36}- {1/x^2}) /  ({1/6}+{1/x}) = ({1/6}-{1/x})

anonymous · Answer

$$a^2-b^2=(a+b)(a-b) $$

anonymous · Answer

$a= \frac 16 $
$b=\frac 1x $

anonymous · Answer
