Abstract

In this paper we establish the general solutions and investigate the Hyers - Ulam stability of the following functional equation f(3x + 2y + z) + f(3x + 2y - z) + f(3x - 2y + z) + f(3x - 2y - z) = 72[f(x + y) + f(x - y)] + 18[f(x + z) + f(x - z)] + 8[f(y + z) + f(y - z)] + 24f(2x) + 4f(2y) - 240f(x) - 160f(y) - 48f(z) in quasi-Banach spaces.a
