D( k )
k = 0
k = 0
k = 0
k in (-oo:0) U (0:+oo)
(8/3)*k-(5/k)-9-3 = 4 // - 4
(8/3)*k-(5/k)-9-4-3 = 0
(8/3)*k-5*k^-1-9-4-3 = 0
8/3*k^1-5*k^-1-16*k^0 = 0
(8/3*k^2-16*k^1-5*k^0)/(k^1) = 0 // * k^2
k^1*(8/3*k^2-16*k^1-5*k^0) = 0
k^1
(8/3)*k^2-16*k-5 = 0
(8/3)*k^2-16*k-5 = 0
DELTA = (-16)^2-(-5*4*(8/3))
DELTA = 928/3
DELTA > 0
k = ((928/3)^(1/2)+16)/(2*(8/3)) or k = (16-(928/3)^(1/2))/(2*(8/3))
k = 3/16*((928/3)^(1/2)+16) or k = 3/16*(16-(928/3)^(1/2))
k in { 3/16*(16-(928/3)^(1/2)), 3/16*((928/3)^(1/2)+16)}
k in { 3/16*(16-(928/3)^(1/2)), 3/16*((928/3)^(1/2)+16) }
