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

(2) For any field k, the ideal (x) in k[x,y] is primary since it is a prime ideal.

... ... etc

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

Now if (x) is prime then obviously (x) is primary BUT ....

How do we show that (x) is prime in k[x, y]?

Would appreciate some help
