Letbe an extension of number fields, and letbe a quadratic polynomial over. Letbe the affine variety defined by. We study the Hasse principle and weak approximation forin three cases. Forandirreducible overand split in, we prove the Hasse principle and weak approximation. Forwith arbitrary, we show that the Brauer-Manin obstruction to the Hasse principle and weak approximation is the only one. Forandirreducible over, we determine the Brauer group of smooth proper models of. In a case where it is non-trivial, we exhibit a counterexample to weak approximation.
