Let R be a ring with identity, C(R) denoted as the center of a ring R, and g(x) 2 C(R)[X]. Ring R is called g(x)-clean rings if for every r 2 R can be expressed as r = u + s with u 2 U(R) and g(s) = 0. Furthermore, ring R is called weakly g(x)-clean rings if for every r 2 R can be expressed as r = u + s or r = u
