a set

[icy cave]

this has infinite many elements

you can draw it though

Ok couldnt tell by the pic

what kind of circle

,, C = { (x,y) \in \mathbb{R}^2 : | : x^2+y^2=2 }

[stiff thunder]

bacc

[icy cave]

of what set

bruh

this is basically solving the equation

x^3-3x^2+2x=0

you can factor x

but the other two sets have infinite many elements/solutions

Yeah but he is saying this example is different.

In the example you gave the set is finite so you can easily list out the elements.

How are you supposed to list out all the points of a circle?

Anyway I think the question you might mean to be asking is list the elements in this set:

$A = {(x,y) \in \mathbb{R}^2 \mid x+y-2=0 \text{ and } x^2+y^2 = 2}$

This set has only 1 element which you can find by finding the intersection of the two curves
