1. **State the problem:** Simplify the expression $$(4 - 5x)(1 - 2x)(3x + 2)$$ by multiplying the three binomials.
2. **Use the distributive property (FOIL for binomials) step-by-step:** First, multiply the first two binomials:
$$ (4 - 5x)(1 - 2x) = 4 \cdot 1 + 4 \cdot (-2x) - 5x \cdot 1 - 5x \cdot (-2x) $$
3. **Calculate each term:**
$$ = 4 - 8x - 5x + 10x^2 $$
4. **Combine like terms:**
$$ = 4 - 13x + 10x^2 $$
5. **Now multiply this result by the third binomial $(3x + 2)$:**
$$ (4 - 13x + 10x^2)(3x + 2) $$
6. **Distribute each term:**
$$ = 4 \cdot 3x + 4 \cdot 2 - 13x \cdot 3x - 13x \cdot 2 + 10x^2 \cdot 3x + 10x^2 \cdot 2 $$
7. **Calculate each product:**
$$ = 12x + 8 - 39x^2 - 26x + 30x^3 + 20x^2 $$
8. **Combine like terms:**
$$ = 30x^3 + (-39x^2 + 20x^2) + (12x - 26x) + 8 $$
$$ = 30x^3 - 19x^2 - 14x + 8 $$
**Final answer:**
$$30x^3 - 19x^2 - 14x + 8$$
