Solution for (x^2-y^2)(y^2-x^2)=9 equation:


Simplifying
(x2 + -1y2)(y2 + -1x2) = 9

Reorder the terms:
(x2 + -1y2)(-1x2 + y2) = 9

Multiply (x2 + -1y2) * (-1x2 + y2)
(x2(-1x2 + y2) + -1y2 * (-1x2 + y2)) = 9
((-1x2 * x2 + y2 * x2) + -1y2 * (-1x2 + y2)) = 9

Reorder the terms:
((x2y2 + -1x4) + -1y2 * (-1x2 + y2)) = 9
((x2y2 + -1x4) + -1y2 * (-1x2 + y2)) = 9
(x2y2 + -1x4 + (-1x2 * -1y2 + y2 * -1y2)) = 9
(x2y2 + -1x4 + (1x2y2 + -1y4)) = 9

Reorder the terms:
(x2y2 + 1x2y2 + -1x4 + -1y4) = 9

Combine like terms: x2y2 + 1x2y2 = 2x2y2
(2x2y2 + -1x4 + -1y4) = 9

Solving
2x2y2 + -1x4 + -1y4 = 9

Solving for variable 'x'.
