How do you determine if a polynomial is the difference of two squares?

    Well, the difference of two squares follows the rule: \[a^2 - b^2 = (a+b)(a-b)\] If you have something like that, like: \[f(x) = x^2 - 4 = x^2 - 2^2 = (x-2)(x+2)\] I don't think I answered what you wanted, but you got it?

    The difference of two square follow this rule: a^2 - b^2 = (a-b) (a+b) Then the polynomial can be arranged to fit the format below: (a-b) (a+b) then that polynomial will end up the difference of 2 squares. Is this what you mean?

    Yeah, they're the same thing... you can eventually manipulate an equation so you just have multiplications. It makes things easier sometimes.
