(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Are the observables corresponding to the d/dx and x^2 operators complementary?

2. Relevant equations

none

3. The attempt at a solution

I know that if the operators do not commute then their corresponding observables are complementary. I just dont know how to show mathematically that they dont commute.
