Abstract
In this paper we derive explicit formulas for computing the roots of a quadratic polynomial with coefficients in a generalized quaternion algebra over any field F with characteristic not 2. We also give some example of applications for the derived formulas, solving equations in the algebra of Hamilton’s quaternions H, in the ring M 2 (R) of 2 × 2 square matrices over R and in quaternion algebras over finite fields.
