Verified Answer :

ok so the fraction can be rewritten as 2(a+1)/(a+1)(a-1) so u cancel the (a+1) and you get 2/a-1 which is (A)

Answer:

A. \(\frac{2}{a-1}\)

Step-by-step explanation:

Given expression is,

\(\frac{2a+2}{a^2-1}\)

\(=\frac{2(a+1)}{a^2-1}\)   ( Taking 2 as common from both terms in numerator )

\(=\frac{2(a+1)}{(a+1)(a-1)}\)  ( a² - b² = (a+b)(a-b) )

\(=\frac{2}{a-1}\)  

Since, the further simplification is not possible,

Hence, option A is correct.
