"Describe all possible values of

for which the term

occurs in the expansion of a

determinant with co-efficient

"

This question is on a sample paper of our linear algebra exam, which I'm studying for, but I don't really understand it. I assume it's to do with the expansion by Minors, but are these the co-ordinates of a single row or column and I'm being asked to find the values? Would someone mind explaining it to me please?? :)

Also, if you'd like to give me a hint as to how to start the question or something like that, I'd really appreciate it!
