On Solving the Pell Equation with Right-Hand Side \(\pm2\) Using Continued Fractions

  • M. E. Changa

摘要

Abstract

The Pell equation with right-hand side \(\pm2\) is considered and a connection is established between its solutions and the convergents of \(\sqrt D\) , which is similar to the well-known statements about the solutions of the Pell equation with right-hand side \(\pm1\) .
