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 but the numerator is not zero at those points.
3. **Factor numerator and denominator:**
$$x^2 + 2x + 1 = (x+1)^2$$
$$x^2 - x - 2 = (x-2)(x+1)$$
4. **Simplify the function:**
$$f(x) = \frac{(x+1)^2}{(x-2)(x+1)}$$
Cancel the common factor $(x+1)$:
$$f(x) = \frac{\cancel{(x+1)}(x+1)}{(x-2)\cancel{(x+1)}} = \frac{x+1}{x-2}$$
5. **Determine vertical asymptotes:**
- The factor $(x+1)$ was canceled, so $x=-1$ is a removable discontinuity, not a vertical asymptote.
- The denominator zero at $x=2$ remains, so $x=2$ is a vertical asymptote.
**Final answer:** The vertical asymptote is at $$x=2$$.
