a x - b y = a^{2} + b^{2}, x + y = 2 a

If sets A and B are defined as
$A = {(x, y) | y = \frac{1}{x}, x \neq 0, x ϵ R}, B = {(x, y) | y = - x, x ϵ R}$ , then

a (x + y) + b (x - y) = a^{2} - a b + b^{2}

a (x + y) - b (x - y) = a^{2} + a b + b^{2}

a (x + y) + b (x - y) = a^{2} - a b + b^{2}

a (x + y) - b (x - y) = a^{2} + a b + b^{2}

x = 1 + a + a^{2} + . . . \infty, (| a | < 1), y = 1 + b + b^{2} + . . . \infty, (| b | < 1),

z = 1 + a b + a^{2} b^{2} + a^{3} b^{3} + . . . \infty
