1. **State the problem:** Find the point where the quadratic function $y = x^2 + 2x + 1$ touches the x-axis.
2. **Recall the formula:** The quadratic touches the x-axis where $y=0$, so solve the equation:
$$x^2 + 2x + 1 = 0$$
3. **Factor the quadratic:**
$$x^2 + 2x + 1 = (x+1)^2$$
4. **Set the factor equal to zero:**
$$(x+1)^2 = 0$$
5. **Solve for $x$:**
$$x + 1 = 0 \\ x = -1$$
6. **Interpretation:** The quadratic touches the x-axis at $x = -1$, and since it is a perfect square, it only touches (tangent) at this point.
7. **Find the corresponding $y$ value:**
$$y = (-1)^2 + 2(-1) + 1 = 1 - 2 + 1 = 0$$
**Final answer:** The quadratic touches the x-axis at the point $(-1, 0)$.
