Question:

In general, it is difficult to show that two matrices are similar. However, if two similar matrices are diagonalizable, the task becomes easier. Show that A and B are similar by showing that they are similar to the same diagonal matrix. Then find an invertible matrix P such that P^-1AP = B.

-3 -2 B = 5 -1 -1
