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. So the factored form of the equation is:
(m + 7)(m + 1) = 0
Setting each factor to zero gives us:
m + 7 = 0 or m + 1 = 0
Which simplifies to:
m = -7 or m = -1
Therefore, the solutions are m = -7 or m = -1.
