Hi again!
I have a couple questions that I need help with.
The first one I have the answer to but need a formula/proof/method/working/whatever you call it, to go with it.
The question:
The sum of a number and its reciprocal is 10/3. What is the number?
My answer:
3
--------------------------------
This next question confuses the (blank) out of me:
The question
((x^2 + 5x + 4)/(x + 3)^2)/((x + 1)/(x^2 - 9))
My answer:
???
Thank you in advance for your help!

No "proof" needed, just write the equation out:
The sum of a number and it's reciprocal:
;
Is equal to :
.
You can solve the above yes?
As to your second problem, simply rewrite the problem by "flipping" the denominator, so instead of dividing by a rational, you are multiplying by its reciprocal.
Ahhhh....
I think I get it!
So.....
Would the answer to the question
((x^2 + 5x + 4)/(x + 3)^2)/((x + 1)/(x^2 - 9))
be: x^2+x-12?

I think I can handle working though my first question now, thanks to both your help, ANDS! and earboth!
Thank you for your help guys!
