Abstract: We give an in depth description of indefinite binary quadratic forms with a particular emphasis on Zagier’s reduction theory for such forms. We also connect this theory with the theory of minus continued fractions and as a further application we offer a constructive approach to solving the Fermat-Pell Equation in two different settings.
