Question

I am confused in this question...because according to me A does not satisfy the condition of ideal. It means A is not ideal. But given that A is ideal.

A is ideal of Euclidean ring R.

I attach a solution but i cant understand it... Please check and tell me is it true.. or send me a clear and well explained solution.

How we show this.
