    Looks like it should be

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

    expanding that gives x^2+2+\frac{1}{x^2}

    and then integrating gives.....

    Misprint seems highly likely?

    Since \frac{dy}{dx}=(x+\frac{1}{x})^2

    \rightarrow \frac{dy}{dx}=x^2+2+\frac{1}{x^2  }

    \rightarrow y=\frac{x^3}{3}+2x-\frac{1}{x}+C

    Wrong arrow I know, sorry.
