Evaluate the following integral on the interval

(0; + \infty)

.

\int (\frac{1}{x} + \frac{1}{x + 1} + \frac{x}{x^{2} + 2}) d x

\ln x + \ln (x + 1) + \frac{1}{2} \ln (x^{2} + 2) + c; c \in R

\ln x + \ln (x + 1) + \frac{1}{2} x^{2} \ln (x^{2} + 2) + c; c \in R

\frac{2}{x^{2}} + \frac{1}{\frac{1}{2} x^{2} + x} + \frac{\frac{1}{2} x^{2}}{\frac{1}{3} x^{3} + 2 x} + c; c \in R

\ln x + \ln (x + 1) + \frac{3 x}{2 (x^{2} + 6)} + c; c \in R
