2/x-16*x^-2-4+16 = 0

2*x^-1-16*x^-2+12 = 0

t_1 = x^-1

2*t_1^1-16*t_1^2+12 = 0

2*t_1-16*t_1^2+12 = 0

DELTA = 2^2-(-16*4*12)

DELTA = 772

DELTA > 0

t_1 = (772^(1/2)-2)/(-16*2) or t_1 = (-772^(1/2)-2)/(-16*2)

t_1 = (2*193^(1/2)-2)/(-32) or t_1 = (-2*193^(1/2)-2)/(-32)

t_1 = (2*193^(1/2)-2)/(-32)

x^-1-((2*193^(1/2)-2)/(-32)) = 0

1*x^-1 = (2*193^(1/2)-2)/(-32) // : 1

x^-1 = (2*193^(1/2)-2)/(-32)

-1 < 0

1/(x^1) = (2*193^(1/2)-2)/(-32) // * x^1

1 = ((2*193^(1/2)-2)/(-32))*x^1 // : (2*193^(1/2)-2)/(-32)

-32*(2*193^(1/2)-2)^-1 = x^1

x = -32*(2*193^(1/2)-2)^-1

t_1 = (-2*193^(1/2)-2)/(-32)

x^-1 = (-2*193^(1/2)-2)/(-32)

-1 < 0

1/(x^1) = (-2*193^(1/2)-2)/(-32) // * x^1

1 = ((-2*193^(1/2)-2)/(-32))*x^1 // : (-2*193^(1/2)-2)/(-32)

-32*(-2*193^(1/2)-2)^-1 = x^1

x = -32*(-2*193^(1/2)-2)^-1

x in { -32*(2*193^(1/2)-2)^-1, -32*(-2*193^(1/2)-2)^-1 }
