Subproblem 2
Set the factor '(2sy + -2xy + x2 + y2)' equal to zero and attempt to solve:

Simplifying
2sy + -2xy + x2 + y2 = 0

Solving
2sy + -2xy + x2 + y2 = 0

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

Add '-2sy' to each side of the equation.
2sy + -2xy + x2 + -2sy + y2 = 0 + -2sy

Reorder the terms:
2sy + -2sy + -2xy + x2 + y2 = 0 + -2sy

Combine like terms: 2sy + -2sy = 0
0 + -2xy + x2 + y2 = 0 + -2sy
-2xy + x2 + y2 = 0 + -2sy
Remove the zero:
-2xy + x2 + y2 = -2sy

Add '2xy' to each side of the equation.
-2xy + x2 + 2xy + y2 = -2sy + 2xy

Reorder the terms:
-2xy + 2xy + x2 + y2 = -2sy + 2xy

Combine like terms: -2xy + 2xy = 0
0 + x2 + y2 = -2sy + 2xy
x2 + y2 = -2sy + 2xy

Add '-1x2' to each side of the equation.
x2 + -1x2 + y2 = -2sy + 2xy + -1x2

Combine like terms: x2 + -1x2 = 0
0 + y2 = -2sy + 2xy + -1x2
y2 = -2sy + 2xy + -1x2

Add '-1y2' to each side of the equation.
y2 + -1y2 = -2sy + 2xy + -1x2 + -1y2

Combine like terms: y2 + -1y2 = 0
0 = -2sy + 2xy + -1x2 + -1y2

Simplifying
0 = -2sy + 2xy + -1x2 + -1y2
