ARE YOU SERIOUS? IF YOU ARE, PREPARE YOURSELF!!!!!!!!!!!!!!!!!!!.

 

Solve for x:
(x+y)^40 = 0

Taking 40^th roots gives 0 times the 40^th roots of unity:
x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0

Subtract y from both sides:
x = -y or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0

Subtract y from both sides:
x = -y or x = -y or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0

Subtract y from both sides:
x = -y or x = -y or x = -y or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0

Subtract y from both sides:
