INTRODUCTION |
The Ternary Quadratic Diophantine Equation offers an unlimited field for research because of their variety [1, 2]. For an extensive review of various problems, one may refer [3-23]. This communication concerns with yet another interesting Ternary Quadratic Equation for determining its infinitely many non-zero integral solutions. |
II.METHOD OF ANALYSIS |
The ternary quadratic equation to be solved in integers is |
It is noted that (1) can be satisfied by the following triples of integers (1141a,379a,419a),(-2294A,1895A,2095A),(151a,a,77a),(746A,5A,385A),(305T,94T,115T), (-679A,470A,575A),(346a,91a,137a),(-911A,455A,685A),(1469A,355A,595A), (-166a,71a,119a),(481a,70a,215a),(-71T,14T,43T). |
Now,introducing the linear transformations |
ïÿýïÿý = ïÿýïÿý + ïÿýïÿý ; ïÿýïÿý = ïÿýïÿý − ïÿýïÿý (2) |
which is equivalent to the system of equations |
It is observed that, by rewriting (4) suitably, one may arrive at the following three patterns of solutions to (1). |
However , we have another solution pattern which is illustrated below: |
III.CONCLUSION |
To conclude, one may search for other patterns of solutions to the equation under consideration. |
