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

Reorder the terms:
2x2 + -2x2 + -1y + y2 = 2xy + -2x2

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

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

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

Add '-1y2' to each side of the equation.
