I have not checked my answer and there is a lot of room for careless error but this is what I did.

Steps.

1)   I used polynomial division to get the remainder - which I got as     (5k-2)/4

2)   then I looked at

      \(\frac{5k-2}{4}=\frac{15-i}{32}\\ ...\\ 40k=31-i\\ k=\frac{31}{40}-\frac{i}{40}\)
