We are concerned with the oscillation of the forced second-order neutral nonlinear differential equations with delayed argument in the form (r(t)(x(t) + a(t)x(sigma(t)))')' + p(t)f(x(tau(t))) + sum from i=1 to n qi(t)|x(t)|~((lambda)_i)sngx(t) velence e(t). No restriction is imposed on the potentials p(t), q_(i)(t), ande(t) to be nonnegative. Our methodology is somewhat different from those of previous authors.
