30 days free to try out the Estude Matemática platform: https://estude.link/ytqdd013 ↓ Today's question in the “Question of the Day” series is number 50 from the 2020 edition of the ITA (Instituto Tecnológico da Aeronáutica) entrance exam. This is a polynomial question that can be solved in many different ways, but I chose a very elegant way that uses Girard's relations (sum and product) and also the factored form. You'll like it!
