x in (-oo:+oo)
180/(2*45) = 2*x^2-(4*y) // - 2*x^2-(4*y)
4*y-(2*x^2)+180/(2*45) = 0
4*y-2*x^2+180/(2*45) = 0
-2*x^2 = -(4*y+2) // : -2
x^2 = (4*y+2)/2
x^2 = (4*y+2)/2 // ^ 1/2
abs(x) = ((4*y+2)^(1/2))/(2^(1/2))
x = ((4*y+2)^(1/2))/(2^(1/2)) or x = -(((4*y+2)^(1/2))/(2^(1/2)))
x in { ((4*y+2)^(1/2))/(2^(1/2)), -(((4*y+2)^(1/2))/(2^(1/2))) }
