  Nonlocal cosmological models with quadratic potentials are considered. We
study the action with an arbitrary analytic function F(\Box_g), which has both
double and simple roots. The formulae for nonlocal energy-momentum tensor,
which correspond to double roots, have been obtained. The way to find
particular solutions for nonlocal Einstein equations in the case when F(\Box_g)
has both simple and double roots has been proposed. One and the same functions
solve the initial nonlocal Einstein equations and the obtained local Einstein
equations.
