1. **State the problem:** Simplify the expression $$\frac{2m - 10}{m^2 - 5m - 24} + \frac{4m + 28}{m^2 - 5m - 24}$$ where both fractions have the same denominator.
2. **Formula and rules:** When adding fractions with the same denominator, add the numerators and keep the denominator the same:
$$\frac{a}{c} + \frac{b}{c} = \frac{a + b}{c}$$
3. **Add the numerators:**
$$\frac{(2m - 10) + (4m + 28)}{m^2 - 5m - 24} = \frac{2m - 10 + 4m + 28}{m^2 - 5m - 24}$$
4. **Simplify the numerator:**
$$2m + 4m = 6m$$
$$-10 + 28 = 18$$
So,
$$\frac{6m + 18}{m^2 - 5m - 24}$$
5. **Factor numerator and denominator:**
Numerator:
$$6m + 18 = 6(m + 3)$$
Denominator:
$$m^2 - 5m - 24$$
Find factors of -24 that sum to -5: -8 and +3
$$m^2 - 5m - 24 = (m - 8)(m + 3)$$
6. **Rewrite the fraction:**
$$\frac{6(m + 3)}{(m - 8)(m + 3)}$$
7. **Cancel common factors:**
$$\frac{6\cancel{(m + 3)}}{(m - 8)\cancel{(m + 3)}} = \frac{6}{m - 8}$$
8. **Final answer:**
$$\boxed{\frac{6}{m - 8}}$$
This is the simplified form of the original expression.
