1. **State the problem:** Solve the inequality $x^2 - 14x > 0$.
2. **Rewrite the inequality:** Factor the left side:
$$x^2 - 14x = x(x - 14)$$
So the inequality becomes:
$$x(x - 14) > 0$$
3. **Analyze the inequality:** The product of two factors is greater than zero when both factors are positive or both are negative.
4. **Case 1: Both factors positive**
$$x > 0 \quad \text{and} \quad x - 14 > 0$$
$$x > 0 \quad \text{and} \quad x > 14$$
Combined:
$$x > 14$$
5. **Case 2: Both factors negative**
$$x < 0 \quad \text{and} \quad x - 14 < 0$$
$$x < 0 \quad \text{and} \quad x < 14$$
Combined:
$$x < 0$$
6. **Combine solutions:**
$$x < 0 \quad \text{or} \quad x > 14$$
7. **Final answer:**
$$\boxed{x < 0 \text{ or } x > 14}$$
