x in (-oo:+oo)
Y = ((4*x)/2)*x-6 // - ((4*x)/2)*x-6
Y-(((4*x)/2)*x)+6 = 0
Y-2*x^2+6 = 0
-2*x^2 = -(Y+6) // : -2
x^2 = (Y+6)/2
x^2 = (Y+6)/2 // ^ 1/2
abs(x) = ((Y+6)^(1/2))/(2^(1/2))
x = ((Y+6)^(1/2))/(2^(1/2)) or x = -(((Y+6)^(1/2))/(2^(1/2)))
x in { ((Y+6)^(1/2))/(2^(1/2)), -(((Y+6)^(1/2))/(2^(1/2))) }
