1. **State the problem:** Expand and fully simplify the expression $$(2x - 1)(x - 5)(x + 6)$$.
2. **Formula and rules:** To expand the product of multiple binomials, first multiply two binomials using the distributive property (FOIL method), then multiply the result by the remaining binomial.
3. **Step 1: Multiply the first two binomials:**
$$(2x - 1)(x - 5) = 2x \cdot x + 2x \cdot (-5) - 1 \cdot x - 1 \cdot (-5)$$
$$= 2x^2 - 10x - x + 5 = 2x^2 - 11x + 5$$
4. **Step 2: Multiply the result by the third binomial:**
$$(2x^2 - 11x + 5)(x + 6) = 2x^2 \cdot x + 2x^2 \cdot 6 - 11x \cdot x - 11x \cdot 6 + 5 \cdot x + 5 \cdot 6$$
$$= 2x^3 + 12x^2 - 11x^2 - 66x + 5x + 30$$
5. **Step 3: Combine like terms:**
$$2x^3 + (12x^2 - 11x^2) + (-66x + 5x) + 30 = 2x^3 + x^2 - 61x + 30$$
**Final answer:**
$$\boxed{2x^3 + x^2 - 61x + 30}$$
