Abstract: Polynomials $ {P_n}(x)$ generated by a three-term recurrence relation with suitably restricted coefficients are orthogonal with respect to a (perhaps unknown) distribution $ d\alpha (x)$ on the real line. An evaluation of $ \int_a^b {P_n^2(x)d\alpha (x)} $ is given in terms of the coefficients in the recurrence relation. Knowledge of the distribution $ d\alpha (x)$ is unnecessary.
