Solution for k-2=12/k equation: 


D( k )

k = 0

k = 0

k = 0

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

k-2 = 12/k // - 12/k

k-(12/k)-2 = 0

k-12*k^-1-2 = 0

1*k^1-12*k^-1-2*k^0 = 0

(1*k^2-2*k^1-12*k^0)/(k^1) = 0 // * k^2

k^1*(1*k^2-2*k^1-12*k^0) = 0

k^1

k^2-2*k-12 = 0

k^2-2*k-12 = 0

DELTA = (-2)^2-(-12*1*4)

DELTA = 52

DELTA > 0

k = (52^(1/2)+2)/(1*2) or k = (2-52^(1/2))/(1*2)

k = (2*13^(1/2)+2)/2 or k = (2-2*13^(1/2))/2

k in { (2-2*13^(1/2))/2, (2*13^(1/2)+2)/2} 

k in { (2-2*13^(1/2))/2, (2*13^(1/2)+2)/2 }
