Module 9 Evidence

The ninth module was not the hardest module, although I found some exercises to be challenging, I understood the procedure since day one, the issue was that I didn't comprehend the reason why we did those procedures, unlike the rest of the course in which procedures seem much more obvios and logical, at the end I practiced the Descartes Rule of Signs a lot and found out what was happening, and why there were many zeros in the polynomials, this particular problem was the one that have me those answers and finally let me finish the course with great advancements in my scholar life.
