%X We give sufficient conditions so that all solutions of differential equations (r(t)y¡ä¡ä(t))¡ä+q(t)k(y¡ä(t))+p(t)y¦Á(g(t))=f(t),  t¡Ýt0, and (r(t)y¡ä¡ä(t))¡ä+q(t)k(y¡ä(t))+p(t)h(y(g(t)))=f(t),  t¡Ýt0, are nonoscillatory. Depending on these criteria, some results which exist in the relevant literature are generalized. Furthermore, the conditions given for the functions k and h lead to studying more general differential equations.
