In 1981, Beukers used a hypergeometric method for proving that the
well-known generalized Ramanujan-Nagell equation
has at most one solution in positive integers x and n,
where C and p are previously fixed, with a few
exceptions.
In this note, we give an elementary proof of this result when n is
even as well as the complete solution of a such equation when C
is a power of 2009. Moreover, we prove that the previous result is
surprisingly connected with the title equation, which allow us to find
all solutions for that equation.
