2)A)

find the definative polinomial and the minimal polinomial of

find the primary decomposition of in this case,and write the diagonal block matrices

similar to A

?

B)

find the jordan form of A defined in part A

and find the transformation matrices to the basis for which it represented in jordan form.

how i tried:

regarding A:

how i tried:

|tI-A|= = = =

=

there are some roots possible by theory t=1,-1,+28,-28

t=1: 1-8+24-28

t=-1: -1-8-24-28

from the calculator the other dont work too

??
