In order to solve an equation by factoring, it should be that the equation is equal to zero.
m^2 + 8m + 7 = 0
For this case we have, to do completing the square in order to factor this equation.
<span>
m^2 + 8m = -7
</span><span>m^2 + 8m + 16 = -7 +16
</span><span>(m+4) (m+4) = 9
</span><span>(m+4)^2 = 9

Take the square root of both sides,
m+4 = 3
m = -1</span><span>
</span>
