1. **State the problem:** Solve the quadratic equation $$8)\ 2m^2 - 7m - 13 = -10$$.
2. **Rewrite the equation:** Move all terms to one side to set the equation equal to zero.
$$2m^2 - 7m - 13 + 10 = 0$$
$$2m^2 - 7m - 3 = 0$$
3. **Factor the quadratic:** Find two numbers that multiply to $2 \times (-3) = -6$ and add to $-7$.
These numbers are $-6$ and $-1$.
Rewrite the middle term:
$$2m^2 - 6m - m - 3 = 0$$
Group terms:
$$ (2m^2 - 6m) - (m + 3) = 0$$
Factor each group:
$$2m(m - 3) - 1(m + 3) = 0$$
Note the signs do not match for factoring by grouping, so try factoring directly:
$$(2m - 1)(m + 3) = 0$$
4. **Solve each factor:**
Set each factor equal to zero:
$$2m - 1 = 0 \implies m = \frac{1}{2}$$
$$m + 3 = 0 \implies m = -3$$
5. **Conclusion:** The solutions to the equation are $$m = \frac{1}{2}$$ and $$m = -3$$.
Your solution is correct.
