1. Factor the polynomial completely using the given factor and division: 

\(x^4 - 3x^3 - 36x^2 + 68x + 240; \quad x^2 - 4x - 12\)

**Explanation:** 

This problem involves factoring a polynomial completely using a provided factor of \(x^2 - 4x - 12\). The task includes polynomial division to break down the given polynomial into simpler components. 

### Steps:

1. **Identify the Given Factor:** 
   - The polynomial \(x^2 - 4x - 12\) is provided as a factor.

2. **Polynomial Long Division or Synthetic Division:**
   - Use either polynomial long division or synthetic division to divide \(x^4 - 3x^3 - 36x^2 + 68x + 240\) by \(x^2 - 4x - 12\).

3. **Find the Quotient:**
   - The quotient obtained after division, when multiplied with the given factor, should give the original polynomial.

4. **Factor Completely:**
   - Check if the quotient and any resultant polynomials can be factored further into simpler binomials or trinomials.
