Could someone please explain this video in an easier-to-understand way? I've watched it several times, and still don't get how to find the rational roots of a polynomial =(

Question

Thank you so much for your help!

Answer 1

Unfortunately you can not post a link here.

Answer 2

Oh, I didn't know that, I'm really sorry! The video is called "rational zeros test" and the youtube channel is "lfhsmah"

Answer 3

I could not find the one you said but this one seems pretty well explained:
