Homework Help: algebra

Posted by Theresse on Saturday, September 29, 2012 at 2:39pm.

in solving the equation (x +2)(x - 2) = 32 eric stated the solution to be x + 2 = 32 => x = 30 or x- 2 = 32 => x = 34. however at least one of these solutions fails to work when plugged back into the equation. why is that? please help eric to understand the problem better; solve the problem yourself and explain your reasoning.

i tried using foil that doesnt appear to work
