Question
![**Matrix Diagonalization Task**
Consider the matrix
\[ A = \begin{bmatrix} -4 & 5 & 5 & 5 \\ -6 & 2 & 6 & 6 \\ -7 & 0 & 3 & 7 \\ -8 & 5 & 5 & 9 \end{bmatrix} \]
which has eigenvalues \(\lambda = 1, 2, 3, 4\).
Now, examine the matrix
\[ B = \begin{bmatrix} -3 & 5 & 5 & 5 \\ -6 & 3 & 6 & 6 \\ -7 & 0 & 4 & 7 \\ -8 & 5 & 5 & 10 \end{bmatrix} \]
Is matrix \(B\) diagonalizable? Without calculating eigenvectors or eigenvalues, explain why or why not (note: you will lose points if you calculate eigenvectors or eigenvalues).
**Explanation Task:**
To determine if matrix \(B\) is diagonalizable, consider the properties it should possess related to its eigenvalues and the associated algebraic and geometric multiplicities. You may also explore other mathematical relationships or properties to justify your reasoning without direct computation of eigenvalues or eigenvectors.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb04829d0-4645-426e-bf1a-7ada40b0786f%2Fee6b4643-d3d2-4617-b5cc-6fae8f9952f4%2Fgpsud07_processed.jpeg&w=3840&q=75)
