Hi guys, Im doing algebraic fractions and I got this fraction:

Question

(x^2+2x+1)/(x^2+1) ,
but the answers say that this is correct:
(x^2-1)/(x^2-2x-1).

So is (x^2+2x+1)/(x^2+1) = (x^2-1)/(x^2-2x-1)?

Thanks in advance

Answer 1

see
(x^2+2x+1)/(x^2+1)
((x^2+x)+(x+1)]/(x^2+1)
x(x+1)+1(x+1)/(x^2+1)
(x+1)^2/(x^2+1)....What i see

Answer 2

Hard to tell without the original question.
As collins pointed out, your answer and the apparent correct answer do not match.

State the original question and how you got your answer.
