**Linear Transformations and Eigenvalues: A Detailed Example**

Consider the linear transformation \( T: \mathbb{R}^n \to \mathbb{R}^n \) whose matrix \( A \) relative to the standard basis is given:
\[ A = \begin{bmatrix} 3 & -1 \\ 2 & 6 \end{bmatrix} \]

(a) **Finding Eigenvalues:**
To find the eigenvalues of matrix \( A \), solve for:
\[
(\lambda_1, \lambda_2) = \boxed{\phantom{\text{Eigenvalues}}}
\]
(Enter your answers from smallest to largest.)

(b) **Finding Basis for Each Corresponding Eigenspace:**
For each eigenvalue found, determine the basis for the corresponding eigenspace.

For the eigenvalue \(\lambda_1\):
\[
B_1 = \left\{ \boxed{\phantom{\text{Basis vector for } \lambda_1}} \right\}
\]

For the eigenvalue \(\lambda_2\):
\[
B_2 = \left\{ \boxed{\phantom{\text{Basis vector for } \lambda_2}} \right\}
\]

(c) **Finding the Matrix \( A' \) Relative to Basis \( B' \):**
Where \( B' \) is made up of the basis vectors found in part (b), transform matrix \( A \) to its representation \( A' \) relative to the new basis \( B' \):

\[
A' = \begin{bmatrix}
\boxed{\phantom{\text{Value}}} & \boxed{\phantom{\text{Value}}} \\
\boxed{\phantom{\text{Value}}} & \boxed{\phantom{\text{Value}}}
\end{bmatrix}
\]

This example guides you through the process of finding eigenvalues and eigenspaces for a given matrix, and how to transform a matrix relative to a new basis.
