Since we know about "i", why not factor it into (x+10i)(x-10i)?

i = when Euclidian geometry experiences an added dimension. You have left the 2D plane and started to move on the Z axis

After listening to you many times, these rules that have forgotten are coming back and I can follow along flawlessly. I'm sure you are a teacher. Great content.
