D( w )
w = 0
w = 0
w = 0
w in (-oo:0) U (0:+oo)
6*w-((23/5)*w)-w-(4/w)-15-3 = 0
6*w+(-23/5)*w-w-4*w^-1-15-3 = 0
2/5*w^1-4*w^-1-18*w^0 = 0
(2/5*w^2-18*w^1-4*w^0)/(w^1) = 0 // * w^2
w^1*(2/5*w^2-18*w^1-4*w^0) = 0
w^1
(2/5)*w^2-18*w-4 = 0
(2/5)*w^2-18*w-4 = 0
DELTA = (-18)^2-(-4*4*(2/5))
DELTA = 1652/5
DELTA > 0
w = ((1652/5)^(1/2)+18)/(2*(2/5)) or w = (18-(1652/5)^(1/2))/(2*(2/5))
w = 5/4*((1652/5)^(1/2)+18) or w = 5/4*(18-(1652/5)^(1/2))
w in { 5/4*(18-(1652/5)^(1/2)), 5/4*((1652/5)^(1/2)+18)}
w in { 5/4*(18-(1652/5)^(1/2)), 5/4*((1652/5)^(1/2)+18) }
