1. **Problem:** Solve the quadratic equation $x^2 + x - 6 = 0$ by factoring.
2. **Formula and rules:** To solve quadratic equations by factoring, we look for two numbers that multiply to the constant term and add to the coefficient of $x$.
3. **Step 1: Factor the quadratic.**
$$x^2 + x - 6 = (x + 3)(x - 2) = 0$$
4. **Step 2: Set each factor equal to zero.**
$$x + 3 = 0 \quad \text{or} \quad x - 2 = 0$$
5. **Step 3: Solve each equation.**
$$x = -3 \quad \text{or} \quad x = 2$$
6. **Answer:** The solutions are $x = -3$ and $x = 2$.
This is the first problem solved in detail as requested.
