Definition: A Diophantine equation is a polynomial equation with integer coefficients where the goal is to find integer solutions.

The solutions to Diophantine equations can be found using various techniques, including: diophantine equation ppt

Existence of Solutions: A solution exists if and only if the greatest common divisor (GCD) of . Mathematically: Definition : A Diophantine equation is a polynomial

  1. Solve ( 12x + 18y = 30 ) (easy).
  2. Find all integer solutions to ( 7x + 11y = 3 ) (medium).
  3. Show ( x^2 + y^2 = 3 ) has no integer solutions modulo 4 (harder).
  4. Find one Pythagorean triple with hypotenuse 65 (medium).
  5. (Challenge) Prove that ( x^2 + y^2 + z^2 = 2xyz ) has only trivial integer solutions (requires infinite descent).

7. Example: Generating primitive Pythagorean triples

Let m>n>0 be coprime and of opposite parity. Then: x = m^2 - n^2, y = 2mn, z = m^2 + n^2 All primitive integer solutions (up to order and signs) come from such m,n. Solve ( 12x + 18y = 30 ) (easy)
