Solution for 1/k-3/8k equation: 


D( k )

k = 0

k = 0

k = 0

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

1/k-((3/8)*k) = 0

(-3/8)*k+1/k = 0

1*k^-1-3/8*k^1 = 0

(1*k^0-3/8*k^2)/(k^1) = 0 // * k^2

k^1*(1*k^0-3/8*k^2) = 0

k^1

(-3/8)*k^2+1 = 0

(-3/8)*k^2+1 = 0

DELTA = 0^2-(1*4*(-3/8))

DELTA = 3/2

DELTA > 0

k = ((3/2)^(1/2)+0)/(2*(-3/8)) or k = (0-(3/2)^(1/2))/(2*(-3/8))

k = -4/3*(3/2)^(1/2) or k = 4/3*(3/2)^(1/2)

k in { -4/3*(3/2)^(1/2), 4/3*(3/2)^(1/2)} 

k in { -4/3*(3/2)^(1/2), 4/3*(3/2)^(1/2) }
