    What does it mean for an extension field \(E\) of a field \(F\) to be a simple extension of \(F\text{?}\)

    2

    What is the definition of a minimal polynomial of an element \(\alpha\in E\text{,}\) where \(E\) is an extension of \(F\text{,}\) and \(\alpha\) is algebraic over \(F\text{?}\)

    3

    Describe how linear algebra enters into this chapter. What critical result relies on a proof that is almost entirely linear algebra?
