#### Problem 2: Diagonalization of Transformations
For the following transformations, find a basis \( B \) such that the matrix representing \( T \) is diagonal.
#### (a) Transformation in \(\mathbb{R}^2\)
\[ T(x, y) = (3x + 2y, 2x + 3y) \]
Find a basis \( B \) for which the matrix representing \( T \) is diagonal.
#### (b) Transformation for Polynomial Coefficients
\[ T(a_0 + a_1x) = a_0 - a_1x \]
Find a basis \( B \) for which the matrix representing \( T \) is diagonal.
#### (c) Transformation in \(\mathbb{R}^3\)
\[ T(x, y, z) = (-2x + 2y - 3z, 2x + y - 6z, -x - 2y) \]
For this transformation, show the steps of calculating the determinant until you obtain a simplified cubic polynomial. After getting the cubic, it can be written as:
\[ -(\lambda + 3)^2(\lambda - 5) \]
Continue solving from this form.
In this problem, we are focusing on finding an eigenbasis for each transformation that will allow the matrix \( T \) to be expressed in a diagonal form. This often involves calculating the eigenvalues and eigenvectors for the given matrix representations of the transformations.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1f133c63-1716-41d7-8ec5-0f87428512d1%2F7b8ba2bc-6577-4f67-996a-c638e5c7589f%2Fbwvovr7_processed.png&w=3840&q=75)
