I'm assuming that the problem is }{x^2+1})
right???
Recall that if }{g(x)})
, then
g(x)-f(x)g^{\prime}(x)}{(g(x))^2})
In your case, , which means that =\ln(x+2))
and =x^2+1)
Now derive f and g to get: =\frac{1}{x+2})
and =2x)
Now plug these functions into the formula to get:
(x^2+1)-\ln(x+2)(2x)}{(x^2+1)^2})
Now multiply every term by the inner LCD x+2 and simplify
\ln(x+2)}{(x+2)(x^2+1)^2})
you could perform more simplifications, but that would only change how the answer looks.
