Subproblem 2
Set the factor '(y + -1y2 + x)' equal to zero and attempt to solve:

Simplifying
y + -1y2 + x = 0

Reorder the terms:
x + y + -1y2 = 0

Solving
x + y + -1y2 = 0

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

Add '-1x' to each side of the equation.
x + y + -1x + -1y2 = 0 + -1x

Reorder the terms:
x + -1x + y + -1y2 = 0 + -1x

Combine like terms: x + -1x = 0
0 + y + -1y2 = 0 + -1x
y + -1y2 = 0 + -1x
Remove the zero:
y + -1y2 = -1x

Add '-1y' to each side of the equation.
y + -1y + -1y2 = -1x + -1y

Combine like terms: y + -1y = 0
0 + -1y2 = -1x + -1y
-1y2 = -1x + -1y

Add 'y2' to each side of the equation.
-1y2 + y2 = -1x + -1y + y2

Combine like terms: -1y2 + y2 = 0
0 = -1x + -1y + y2

Simplifying
0 = -1x + -1y + y2
