Asupra metodelor convergente de ordinul trei aplicate la rezolvarea ecuatiilor operationale neliniare

The present paper is concerned to the study of solving operational equation p(x) – 0 by iterative methods when the operation P(x) transfonrs the Danach apace X into Y a space of the some type. We also suppree that P(x) is continouns and admints Preebet,  derivalives to the 3 order, inelusively.
