Solution for (3+x-y)(x+y)= equation: 


Simplifying
(3 + x + -1y)(x + y) = 0

Multiply (3 + x + -1y) * (x + y)
(3(x + y) + x(x + y) + -1y * (x + y)) = 0
((x * 3 + y * 3) + x(x + y) + -1y * (x + y)) = 0
((3x + 3y) + x(x + y) + -1y * (x + y)) = 0
(3x + 3y + (x * x + y * x) + -1y * (x + y)) = 0

Reorder the terms:
(3x + 3y + (xy + x2) + -1y * (x + y)) = 0
(3x + 3y + (xy + x2) + -1y * (x + y)) = 0
(3x + 3y + xy + x2 + (x * -1y + y * -1y)) = 0
(3x + 3y + xy + x2 + (-1xy + -1y2)) = 0

Reorder the terms:
(3x + xy + -1xy + x2 + 3y + -1y2) = 0

Combine like terms: xy + -1xy = 0
(3x + 0 + x2 + 3y + -1y2) = 0
(3x + x2 + 3y + -1y2) = 0

Solving
3x + x2 + 3y + -1y2 = 0
