Post a 50-word response to the following: How do you determine if a polynomial is the difference of two squares? Recall that the differences of squares is: a² - b² = (a - b)(a + b) To determine if a polynomial is the difference of two squares, one of the terms must be negative, and both terms must be perfect square. E.g. x² - 16 x² and 16 are both the perfect squares. Let: a² = x² a = x b² = 16 b = √16 b = 4

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)...
