The answer is x + 8 but I don't know how they got that answer! Thank you for your help! Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! by saying "for all x not equal to -4" they are just saying that division by
zero is not allowed (-4 + 4 in the denominator)
x^2 + 12x +32 /(x + 4)
factoring numerator
(x + 8)(x + 4) / (x + 4)
cancel (x + 4) / (x + 4)
x + 8 answer
