Best ResponseYou've already chosen the best response.1\[\large\rm f'(x)=\frac{2}{(x+1)^2}\]You can apply your exponent rule,\[\large\rm f'(x)=2(x+1)^{2}\]And this allows you to avoid quotient rule a second time if you like. Simply power rule from here.

Best ResponseYou've already chosen the best response.0@triciaal is correct dw:1444282442944:dw And, f''(x) = (4)/(x+1)^3

Best ResponseYou've already chosen the best response.2what I did originally was just use the quotient rule a second time. what @zepdrix suggested was applied here. (remember multiplication and division are complements).
