摘要：
In this manuscript, we introduce a quadratic functional equation of finite variable: & sum;(m)(i=1)phi(2v(i )- & sum;(m )(1 <= i not equal j)v(j)) = (m-7)& sum;(1 <= i<j <= m) phi (v(i) +v(j)) + phi (& sum; (m)(i=1) v(i)) - (m(2) - 9m + 5) & sum;(m)(i=1) phi(v(i)) and examine its Hyers-Ulam stability of this functional equation in Banach space using direct and fixed point method.
