Unformatted text preview: So: (x) - (4) (x - 4)(x + 4) One of the misconceptions that people have when determining the nature of polynomial is that a + b is factorable. Even though it can be factored in terms of i, it's impossible to factor that expression. Also note that you can factor nonnegative and not perfect terms. E.g. x - 2 Let: a = x a = x b = 2 b = 2 So: x - 2 = (x - 2)(x + 2)...
