1. **State the problem:** Simplify the expression $$\frac{3}{2x + 5} - \frac{5}{3x + 2}$$.
2. **Find a common denominator:** The denominators are $2x + 5$ and $3x + 2$. The common denominator is their product: $$(2x + 5)(3x + 2)$$.
3. **Rewrite each fraction with the common denominator:**
$$\frac{3}{2x + 5} = \frac{3(3x + 2)}{(2x + 5)(3x + 2)}$$
$$\frac{5}{3x + 2} = \frac{5(2x + 5)}{(2x + 5)(3x + 2)}$$
4. **Subtract the numerators:**
$$\frac{3(3x + 2) - 5(2x + 5)}{(2x + 5)(3x + 2)}$$
5. **Expand the numerators:**
$$3(3x + 2) = 9x + 6$$
$$5(2x + 5) = 10x + 25$$
6. **Perform the subtraction:**
$$9x + 6 - (10x + 25) = 9x + 6 - 10x - 25 = (9x - 10x) + (6 - 25) = -x - 19$$
7. **Write the simplified expression:**
$$\frac{-x - 19}{(2x + 5)(3x + 2)}$$
8. **Factor out the negative sign in the numerator:**
$$\frac{-(x + 19)}{(2x + 5)(3x + 2)}$$
**Final answer:**
$$\boxed{\frac{-(x + 19)}{(2x + 5)(3x + 2)}}$$
