1. **State the problem:** Solve the equation $\log_x(8x - 12) = 2$ for $x$.
2. **Rewrite the logarithmic equation in exponential form:** Recall that $\log_a b = c$ means $a^c = b$. So here, $x^2 = 8x - 12$.
3. **Bring all terms to one side to form a quadratic equation:**
$$x^2 - 8x + 12 = 0$$
4. **Factor the quadratic:**
$$(x - 6)(x - 2) = 0$$
5. **Solve for $x$:**
$$x - 6 = 0 \Rightarrow x = 6$$
$$x - 2 = 0 \Rightarrow x = 2$$
6. **Check the domain restrictions:**
- The base $x$ of the logarithm must be positive and not equal to 1: $x > 0$ and $x \neq 1$.
- The argument $8x - 12$ must be positive: $8x - 12 > 0 \Rightarrow x > \frac{12}{8} = 1.5$.
7. **Apply domain restrictions to solutions:**
- $x = 6$ is valid since $6 > 1.5$ and $6 \neq 1$.
- $x = 2$ is valid since $2 > 1.5$ and $2 \neq 1$.
**Final answer:**
$$x = 2 \text{ or } x = 6$$
