Solution for 4h-2/h equation: 


D( h )

h = 0

h = 0

h = 0

h in (-oo:0) U (0:+oo)

4*h-(2/h) = 0

4*h-2*h^-1 = 0

4*h^1-2*h^-1 = 0

(4*h^2-2*h^0)/(h^1) = 0 // * h^2

h^1*(4*h^2-2*h^0) = 0

h^1

4*h^2-2 = 0

4*h^2-2 = 0

DELTA = 0^2-(-2*4*4)

DELTA = 32

DELTA > 0

h = (32^(1/2)+0)/(2*4) or h = (0-32^(1/2))/(2*4)

h = (2^(1/2))/2 or h = (-2^(1/2))/2

h in { (-2^(1/2))/2, (2^(1/2))/2} 

h in { (-2^(1/2))/2, (2^(1/2))/2 }
