We prove the following result: If $(D_1^2 (x) + D_2(x))^n  ∘ α(x)^n  = 0 $ holds for all $x Є R$, then $D_1 = D_2 = 0$. The same is true if $R$ is a 2-torsion free semiprime ring and F(x) ° β(x) = 0 for all x ∈ R, where $F(x) = (D_1^2 (x) + D_2(x)) ∘ α(x),\; x ∈ R$, and $β$ is any automorphism or antiautomorphism on $R$.}, number={10}, journal={Ukrains’kyi Matematychnyi Zhurnal}, author={Baydar, N. and Fošner, A. and Strašek, R.}, year={2014}, month={Oct.}, pages={1436–1440} }
