Best ResponseYou've already chosen the best response.2Again, no. Do you recognize that this is a difference in squares?

Best ResponseYou've already chosen the best response.2Ok. Do you see how s^2 * s^2 = s^4? and that 4 * 4 = 16?

Best ResponseYou've already chosen the best response.0yes so that means the answer has to be A

Best ResponseYou've already chosen the best response.2Nope... \[s^{4}  16 = (s^{2}  4)(s^{2} + 4)\]Now, do you realize that s^2  4 is also a difference in squares?

Best ResponseYou've already chosen the best response.2Alright. The form \[a^{2}  b^{2} = (a + b)(a  b)\]Therefore, \[s^{2}  4 = (s + 2)(s  2) The same for s^2 + 4. It turns imaginary. \[s^{2} + 4 = (s  2i)(s + 2i)
