D( y )

y = 0

y = 0

y = 0

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

y+5/y = 10/8 // - 10/8

y+5/y-(10/8) = 0

y+5/y-5/4 = 0

1*y^1+5*y^-1-5/4*y^0 = 0

(1*y^2-5/4*y^1+5*y^0)/(y^1) = 0 // * y^2

y^1*(1*y^2-5/4*y^1+5*y^0) = 0

y^1

y^2+(-5/4)*y+5 = 0

y^2+(-5/4)*y+5 = 0

DELTA = (-5/4)^2-(1*4*5)

DELTA = -295/16

DELTA < 0
