This example isn't very enlightening, as it's the same as before. I would just delete it, and put the text above the other example. Like

```py
You can choose the other algorithm by setting full=True:

>>> apart(y/(x**2 + x + 1), x)
y/(x**2 + x + 1)
>>> apart(y/(x**2 + x + 1), x, full=True)
RootSum(x**2 + x + 1, Lambda(_a, (-2*_a*y/3 - y/3)/(-_a + x)))
```
