We have:
$\frac{dy}{dx}=1+\frac{1}{{y}^{2}}$
Which is a First Order Separable Ordinary Differential Equation so we can rearrange and "separate the variables":
$\frac{dy}{dx}=\frac{1+{y}^{2}}{{y}^{2}}$

We can manipulate the LHS integral:

Which is now trivial to integrate giving us:
$y-\mathrm{arctan}\left(y\right)=x+C$
Which is the general implicit solution.
