In Chapter 3: Prime Ideals and Maximal Ideals, Exercise 3.6 reads as follows:

-------------------------------------------------------------------------

Determine all the maximal ideals of the ring K[X],

where K is a field and X is an indeterminate.

------------------------------------------------------------------------

Can someone please help me get started on this problem.

I suspect we may be able to use the following theorem/lemma:

"Let I be an ideal of the commutative ring R.

Then I is maximal if and only if R/I is a field."

However I am not sure of exactly how to go about utilising this result.

I would very much appreciate some help.
