1. **State the problem:** Find the vertical asymptotes of the function $$f(x)=\frac{x^2 + 2x + 1}{x^2 - x - 2}$$.
2. **Recall the rule for vertical asymptotes:** Vertical asymptotes occur where the denominator is zero and the numerator is not zero at those points.
3. **Factor the denominator:**
$$x^2 - x - 2 = (x - 2)(x + 1)$$
4. **Set denominator equal to zero to find potential vertical asymptotes:**
$$ (x - 2)(x + 1) = 0 $$
This gives
$$ x = 2 \quad \text{or} \quad x = -1 $$
5. **Check numerator at these points:**
Numerator is $$x^2 + 2x + 1 = (x + 1)^2$$.
At $$x = -1$$, numerator is $$(-1 + 1)^2 = 0$$.
At $$x = 2$$, numerator is $$(2 + 1)^2 = 9 \neq 0$$.
6. **Interpretation:**
Since numerator is zero at $$x = -1$$ and denominator is also zero there, this may be a removable discontinuity, not a vertical asymptote.
At $$x = 2$$, denominator is zero but numerator is not zero, so there is a vertical asymptote at $$x = 2$$.
7. **Final answer:** The vertical asymptote is at $$x = 2$$.
**Answer choice:** c. $$x=2$$
