In this paper, we consider solutions of indefinite binary quadratic forms. Firstly we obtain all integer solutions of the form u2−5uv+v2 = −3, then we find integer solutions of the most general binary quadratic form au2 + buv + cv2 = m by using the Pell equation x2 − dy2 = N, where a, b, c ∈ Z and m,N are nonzero fixed integers. Mathematics Subject Classification: 11E16, 11D09, 11D45, 11J70
