I am trying to find the general solution of this equation, could you help me?

Thank you so much!
A Diophantine equation of second degree is a polynomial equation in two variables, where the variables can only take on integer values. It is named after the ancient Greek mathematician Diophantus and is often expressed in the form of Ax^2 + Bxy + Cy^2 + Dx + Ey + F = 0, where A, B, C, D, E, and F are integers.
A regular algebraic equation can have any real number as a solution, while a Diophantine equation only has integer solutions. Additionally, a Diophantine equation can have multiple solutions, while a regular algebraic equation typically has a unique solution.
Solving Diophantine equations of second degree can be a complex and challenging problem. One method is to use the quadratic formula to find the values of x and y that satisfy the equation. Another approach is to use specific techniques such as completing the square or factoring to simplify the equation and find solutions.
Diophantine equations of second degree have been used in various fields, such as cryptography, coding theory, and number theory. They also have practical applications in engineering and physics, particularly in the analysis of systems with discrete variables.
Yes, there are still many unsolved Diophantine equations of second degree, and some of these have been open for centuries. One famous example is Fermat's Last Theorem, which states that there are no integer solutions to the equation x^n + y^n = z^n for n > 2. Another well-known unsolved Diophantine equation is the Collatz conjecture, which asks whether a specific iterative sequence of numbers always ends in the cycle 4, 2, 1 when starting with any positive integer.
