I need help with some remarks of Bresar on first Weyl Algebras ...

Bresar's remarks on Weyl Algebras are as follows:

View attachment 6237

In the above text from Bresar we read the following: (see (1.4) above)

" ... ... It is straightforward to check that

\(\displaystyle [D, L] = I\)

the identity operator ..."

Can someone please explain exactly why \(\displaystyle [D, L] = I\) ... ... ?

(It looks more like \(\displaystyle [D, L] = 0\) to me?)

Help will be appreciated ...
