Add '-1xy' to each side of the equation.
xy + -1x2 + -1xy + 3y2 = 0 + -1xy

Reorder the terms:
xy + -1xy + -1x2 + 3y2 = 0 + -1xy

Combine like terms: xy + -1xy = 0
0 + -1x2 + 3y2 = 0 + -1xy
-1x2 + 3y2 = 0 + -1xy
Remove the zero:
-1x2 + 3y2 = -1xy

Add 'x2' to each side of the equation.
-1x2 + x2 + 3y2 = -1xy + x2

Combine like terms: -1x2 + x2 = 0
0 + 3y2 = -1xy + x2
3y2 = -1xy + x2

Add '-3y2' to each side of the equation.
3y2 + -3y2 = -1xy + x2 + -3y2

Combine like terms: 3y2 + -3y2 = 0
0 = -1xy + x2 + -3y2

Simplifying
0 = -1xy + x2 + -3y2
