Question

simplify by removing factors of 1
n^2-1/(n+1)^2

Answer 1

You need to start using parenthesis.. I don't know if it is n^2 -(1)/(n+1)^2
or n^(2-1)/(n+1)^2
or ((n^2)-1)/(n+1)^2

lol

Answer 2

only parenthesis is in bottom part (n+1)^2

Answer 3

ok.. If the equation is ((n^2)-1)/(n+1)^2,
then the answer is
(n-1)(n+1)

Answer 4

forgot the slash bar.

(n-1) / (n+1)

Answer 5

sorry
