B. (s  2)(s + 2)
C. (s  i)(s + i)(s  2)(s + 2)
D. (s  2i)(s + 2i)(s  2)(s + 2)

Best ResponseYou've already chosen the best response.0s^2  16 = s^2  4^2 again the same formula a^2 b^2 (s4) (s+4)

Best ResponseYou've already chosen the best response.0because s4 is again (s+2)(s2)

Best ResponseYou've already chosen the best response.0sorry answer is "D" (s  2i)(s + 2i) =(s+4)

Best ResponseYou've already chosen the best response.0\(\large s^416=(s^2)^24^2=(s^24)(s^2+4) \) that first factor is factorable using difference of squares. that second one is factorable involving "sum of squares"
