Best ResponseYou've already chosen the best response.0See how the coefficient on x^2 is a perfect square? (it is 1, which is 1 squared). See also how the constant term is a perfect square? (it is 16, which is 4 squared). Notice also that if you take the coefficient on the middle term (8) and divide it by 2 (giving you 4) and then square it, you get the product of the 1 and the 16? (4 squared is 16) That tells us this trinomial is a perfect square. (x+4)^2 By the zero product property, we know that x+4=0, so x=4
