Solving
x = 0

Move all terms containing x to the left, all other terms to the right.

Simplifying
x = 0

Subproblem 2
Set the factor '(-6 + x + 14x2y2)' equal to zero and attempt to solve:

Simplifying
-6 + x + 14x2y2 = 0

Solving
-6 + x + 14x2y2 = 0

Begin completing the square.  Divide all terms by
14y2 the coefficient of the squared term: 

Divide each side by '14y2'.
-0.4285714286y-2 + 0.07142857143xy-2 + x2 = 0y-2

Move the constant term to the right:

Add '0.4285714286' to each side of the equation.
-0.4285714286y-2 + 0.07142857143xy-2 + 0.4285714286 + x2 = 0.4285714286 + 0y-2

Reorder the terms:
0.4285714286 + 0.07142857143xy-2 + x2 + -0.4285714286y-2 = 0.4285714286 + 0y-2

Combine like terms: 0.4285714286 + 0 = 0.4285714286
0.4285714286 + 0.07142857143xy-2 + x2 + -0.4285714286y-2 = 0.4285714286

The x term is xy-2.  Take half its coefficient (0.5y-2).
Square it (0.25y-4) and add it to both sides.

Add '0.25y-4' to each side of the equation.
0.4285714286 + 0.07142857143xy-2 + x2 + 0.25y-4 + -0.4285714286y-2 = 0.4285714286 + 0.25y-4

Factor a perfect square on the left side:
(x + 0.5y-2)(x + 0.5y-2) = 0.4285714286 + 0.25y-4

Can't calculate square root of the right side.

The solution to this equation could not be determined.

This subproblem is being ignored because a solution could not be determined.
