The matrix equation enters at the final step of the verification computation, where the expression $(XY+YX)v$ is evaluated. Because $X$ and $Y$ are assumed to solve $XY+YX=0$, this expression equals the zero vector, confirming that the ideal generator acts trivially.

Conditions: $X,Y \in M_{n\times n}(\mathbb{C})$.; $XY+YX=0$.; The verification expands $(xy+yx+I)v$ into $(XY+YX)v$.
