D( p )
p = 0
p = 0
p = 0
p in (-oo:0) U (0:+oo)
(5/2)*p+2/p = 3/2 // - 3/2
(5/2)*p+2/p-(3/2) = 0
(5/2)*p+2/p-3/2 = 0
5/2*p^1+2*p^-1-3/2*p^0 = 0
(5/2*p^2-3/2*p^1+2*p^0)/(p^1) = 0 // * p^2
p^1*(5/2*p^2-3/2*p^1+2*p^0) = 0
p^1
(5/2)*p^2+(-3/2)*p+2 = 0
(5/2)*p^2+(-3/2)*p+2 = 0
DELTA = (-3/2)^2-(2*4*(5/2))
DELTA = -71/4
DELTA < 0
p in { }
p belongs to the empty set
