comment Consider the polynomial $f(X) \in \mathbb{Z}[x]$ prove the following
Oh, it was in $\mathbb{Z}$, but your comment is still valid and yes...it was very silly of me to make such a mistake. Thank you!

comment In $\mathbb{R}^3$ find the equation of the circle passing for three points.
It's true, it's an ellipse because in my solution the center is the origin and that's the mistake, right? So to correct my procedure I should find the center, translate it in the origin, do what I did, translate everything back...right? Thank you for your easier solutions!
