Solution for p+2/p=-3 equation: 


D( p )

p = 0

p = 0

p = 0

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

p+2/p = -3 // + 3

p+2/p+3 = 0

1*p^1+2*p^-1+3*p^0 = 0

(1*p^2+3*p^1+2*p^0)/(p^1) = 0 // * p^2

p^1*(1*p^2+3*p^1+2*p^0) = 0

p^1

p^2+3*p+2 = 0

p^2+3*p+2 = 0

DELTA = 3^2-(1*2*4)

DELTA = 1

DELTA > 0

p = (1^(1/2)-3)/(1*2) or p = (-1^(1/2)-3)/(1*2)

p = -1 or p = -2

p in { -2, -1} 

p in { -2, -1 }
