-----
a²-1
Help?

Answer 1

\[\frac{ 2a+2 }{ a²-1 }\]

Answer 2

start with
\[\frac{2(a+1)}{(a+1)(a-1)}\] and then cancel

Answer 3

leaves you with
\[\frac{2}{a-1}\]

Answer 4

Can u simlify more?

Answer 5

not after you write \(\frac{2}{a-1}\) that is the best you can do

Answer 6

Are they also asking for the restrictions on that? If so, that is when the division would be undefined. Does that make sense?

Answer 7

Oh, ok. Thanks!!!
