**Definition**. If $K$ is generated by $F(\alpha)$, then $K$ is a *simple extension* of $F$. **Definition**. If $K$ is generated by $F(\alpha)$, then $K$ is a *simple extension* of $F$.
**Theorem**. Let $F$ be a field, $p(x) \in F[x]$ be irreducible. Then, if $\alpha$ is a root of $p(x)$ and $K$ is an extension of $F$ containing $\alpha$, then $F(\alpha) \cong \frac{F[x]}{(p(x))}$. **Theorem**. Let $F$ be a field, $p(x) \in F[x]$ be irreducible.
