Abstract
A general class of f(R) gravity models with minimally coupling a nonlocal scalar field is considered. The Ostrogradski representation for nonlocal gravitational models with a quadratic potential and the way of its localization are proposed. We study the action with an arbitrary analytic function , which has both simple and double roots. The way of localization allows to find particular solutions of nonlocal equations of gravity.
