To solve by factoring, we need to find two numbers that multiply to 7 and add up to 8. These numbers are 7 and 1.
Therefore, m² + 8m + 7 factors to (m + 7)(m + 1) = 0.
Setting each factor to zero:
m + 7 = 0 or m + 1 = 0
m = -7 or m = -1
So the solutions are m = -7 or m = -1.
Therefore, the correct response is -7, -1.
