### Linear Algebra Example: Eigenvalues and Eigenvectors

Given the matrix:

\[ A = \begin{bmatrix}
2 & 4 \\
0 & -2
\end{bmatrix} \]

#### (a) Find the characteristic polynomial of \( A \)
\[ p(x) = \, \]
*(Box where students can input the characteristic polynomial equation)*

#### (b) Find the eigenvalues of \( A \) and bases for the associated eigenspaces:

- **Smallest eigenvalue**
  \[ \boxed{} \]

  Basis for the associated eigenspace:
  \[ \boxed{} \]

- **Largest eigenvalue**
  \[ \boxed{} \]

  Basis for the associated eigenspace:
  \[ \boxed{} \]

This exercise guides students through finding the characteristic polynomial, eigenvalues, and associated eigenspaces of a given matrix \( A \).
