comment How to count algebraic multiplicities to show $\nexists$ an eigenbasis for $A$?
Kind of, but to me, that's a bit strange way of seeing it. Rather, you have only one eigenvector, not three that are equal. But yes, you need three (linearly independent) vectors to span $\mathbb R^3$.

Calculate the eigenvectors and point out that there are too few eigenvectors to form a basis.

By the way, is your polynomial really squarefree?

comment What is the difference between $A^{-1}$ and $A^\Theta$?
Just to be clear; for general matrices $A$, $AA^\Theta = I$ does not hold.

The value of the determinant is not 0, it is $-8x^6$. That does not answer the second part of your question though.
