Will someone check my answers?
Multiply or Divide.
1. 5x+10/x+2 times 2x/4x-10
My answer for that one was (5x)/(2x-5)
2. 3n^2-n/n^2-1 divided by n^2/n+1
My answer was n(3n-1)/(n-1)

re 
My answer for that one was (5x)/(2x-5)
EXCELLENT

anonymous · Answer

for the second one I get this
(3n^2 - 1) / (n(n-1))
how did u get urs?

anonymous · Answer

Honestly I have no idea, Algebra is my worst subject, and it confuses me so much. Thank you for checking for me.

anonymous · Answer

sorry I have a typo above

anonymous · Answer

its (3n-1) / (n(n-1))

anonymous · Answer

Okay thank you. :)

anonymous · Answer

u got the first right so u r good, not bad

campbell_st · Answer

your answer for the 1st problem is correct

anonymous · Answer

you only got the n in the wrong spot for the second answer, can you repeat ur work and see why?

anonymous · Answer

u have in the numerator and I have it in denominr

campbell_st · Answer

the 2nd question has an error. you are correct in factoring 

when you divide by a fraction, flip and multiply

$$\frac{n(3n - 1)}{(n -1)(n + 1)} \times \frac{(n + 1)}{n^2}$$

now remove the common factors leaving 

and see what you have left
