The given expression is:

\[
\frac{x+1}{x+2} + \frac{x-2}{x^2-4}
\]

First, notice that \( x^2 - 4 \) can be factored as:

\[
x^2 - 4 = (x+2)(x-2)
\]

So, the expression becomes:

\[
\frac{x+1}{x+2} + \frac{x-2}{(x+2)(x-2)}
\]

Now, both terms share \( x+2 \) as a common factor in the denominator. We rewrite the second term as:

\[
\frac{x-2}{(x+2)(x-2)} = \frac{1}{x+2}
\]

Thus, the expression simplifies to:

\[
\frac{x+1}{x+2} + \frac{1}{x+2}
\]

Now, since the denominators are the same, we can combine the numerators:

\[
\frac{(x+1) + 1}{x+2} = \frac{x+2}{x+2}
\]

Finally, the expression simplifies to:

\[
1
\]
