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. m^2 + 8m = -7 m^2 + 8m + 16 = -7 +16 (m+4) (m+4) = 9 (m+4)^2 = 9 Take the square root of both sides, m+4 = 3 m = -1
