In this paper, by using the factorization of the companion polynomial of the binary quadratic function [Formula: see text] , [Formula: see text] , [Formula: see text] , m|n, we give a method to compute the exponential sum [Formula: see text] for the quadratic functions f(x), where Tr(⋅) is the trace function from [Formula: see text] to F2. The computation of the exponential sum of quadratic functions with many terms can be transformed to that of some quadratic functions that can be explicitly evaluated by present results. Moreover, the necessary and sufficient condition for [Formula: see text] is given, where g⁎(z) is the generalized reciprocal polynomial of g(z) and f′(z) is the companion polynomial of f(x). As a consequence, the exponential sums S(f,2s) for most binary quadratic functions f(x)∈F2[x] can be computed.
