This article [1] has been retracted by Professor Ravi P Agarwal, Editor-in-Chief of Journal of Inequalities and Applications.

Following publication of this article, it was brought to the attention of the editorial and publishing staff that this article has a substantial overlap with two articles by Hadizadeh, Ghoreishi and Pishbin published in 2011 in Applied Numerical Mathematics [2] and in Electronic Transactions on Numerical Analysis [3].

This is a violation of publication ethics which, in accordance with the Committee on Publication Ethics guidelines, warrants a retraction of the article and a notice to this effect to be published in the journal.
