k in (-oo:+oo)
(1/2)*k-k-(1/2) = (1/4)*(k+1) // - (1/4)*(k+1)
(1/2)*k-((1/4)*(k+1))-k-(1/2) = 0
(-1/4)*(k+1)+(1/2)*k-k-1/2 = 0
k/2-1/4*(k+1)-k-1/2 = 0
(-1/4*2*(k+1))/2+k/2+(2*(-k))/2-1/2 = 0
k-1/4*2*(k+1)+2*(-k)-1 = 0
1/2*k-2*k-1-1/2 = 0
-3/2*k-1-1/2 = 0
-3/2*k-3/2 = 0
(-3/2*k-3/2)/2 = 0
(-3/2*k-3/2)/2 = 0 // * 2
-3/2*k-3/2 = 0
-3/2*k-3/2 = 0 // + 3/2
-3/2*k = 3/2 // : -3/2
k = 3/2/(-3/2)
k = -1
