Calculate all zeros In this math learning video, I (Susanne) explain how to determine the zeros of a function. We use the zero product theorem and polynomial division for a 4th and 3rd degree function. We solve the quadratic equation using Vieta's theorem. Mathematics explained simply. 0:00 Introduction - Calculate all zeros 0:30 Zero product theorem 2:32 4th degree polynomial division 8:16 3rd degree polynomial division 10:43 Vieta's theorem 12:32 Until the next video :) Become a channel member now and support my channel: ➤ https://www.youtube.com/mathematrick/... ???? ????
