Best ResponseYou've already chosen the best response.0I started with long division and got x + 4 as the quotient and 12x  16 as th remainder. I'm not sure if thats correct.

Best ResponseYou've already chosen the best response.0Then I wrote it as the sum of the integral of each term. So like, (int) x + (int) 4 + (int)(12/(x2)^2)  (int) (16/(x2 )^2)

Best ResponseYou've already chosen the best response.0so you have (int) x + (int) 12/(x2) + (int) 8/(x+2)^2 + (int) 4
