@divinedolphin I'm sorry, you are right, Prof. Loh doesn't mention Viete's Formulas in our course, but he does mention it in this explanation video:

I think I got a little confused about where Prof. Loh mentioned it originally. 🙂
The spelling of his name varies; sometimes it's spelled as "Vieta," and sometimes it's spelled as "Viete," as shown in Prof. Loh's video.
