Question
![**Problem Statement:**
Find the (real) eigenvalues and associated eigenvectors of the given matrix **A**. Find a basis of each eigenspace of dimension 2 or larger.
Matrix **A** is given as:
\[
\begin{bmatrix}
1 & 5 & 5 & 5 \\
0 & 2 & 5 & 5 \\
0 & 0 & 3 & 5 \\
0 & 0 & 0 & 4
\end{bmatrix}
\]
**Instructions:**
1. Calculate the eigenvalues of matrix **A**.
2. Determine the associated eigenvectors for each eigenvalue.
3. Identify a basis for each eigenspace with dimension 2 or larger.
**Study Guide:**
- **Eigenvalues** are the values of \( \lambda \) for which the matrix \( A - \lambda I \) is singular. That is, the determinant of \( A - \lambda I \) should be zero.
- **Eigenvectors** are the non-zero vectors **v** that satisfy the equation \( A\mathbf{v} = \lambda\mathbf{v} \).
- **Eigenspace** is the set of all eigenvectors associated with a given eigenvalue, along with the zero vector.
- To find the eigenvalues, solve the characteristic equation \( \det(A - \lambda I) = 0 \).
- For each eigenvalue, substitute \( \lambda \) back into \( A - \lambda I \) to find the associated eigenvectors.
- If an eigenspace has a dimension of 2 or larger, find a basis by identifying a set of linearly independent vectors within that space.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F855c34b7-83bc-4bfb-90ca-8270f5250113%2Feefe899e-57b3-4eb6-91b9-c3458fd59169%2F7x2byzg_processed.png&w=3840&q=75)
