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

D( k )

k = 0

k = 0

k = 0

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

2*k+2/k+2 = -3 // + 3

2*k+2/k+2+3 = 0

2*k^1+2*k^-1+5*k^0 = 0

(2*k^2+5*k^1+2*k^0)/(k^1) = 0 // * k^2

k^1*(2*k^2+5*k^1+2*k^0) = 0

k^1

2*k^2+5*k+2 = 0

2*k^2+5*k+2 = 0

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

DELTA = 9

DELTA > 0

k = (9^(1/2)-5)/(2*2) or k = (-9^(1/2)-5)/(2*2)

k = -1/2 or k = -2

k in { -2, -1/2} 

k in { -2, -1/2 }
