Abstract
We obtain a general solution of the 2-variable quadratic functional equation z(y1 + y2, y3 + y4) + z(y1-y2, y3-y4) = 2z(y1, y3) + 2z(y2, y4) and discuss the stability of the above functional equation, while the quadratic form z(a, b) = aa2 + gab + gc2 is a solution of our functional equation.
