jordan form question
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:
tIA= = = =
=
there are some roots possible by theory t=1,1,+28,28
t=1: 18+2428
t=1: 182428
from the calculator the other dont work too
??

Re: jordan form question
be very careful with your signs when working out determinants. for tI  A, i get:
.
possible rational roots of this are 1,1,2,2,4,4,8,8,16,16. i believe you will find this factors completely.
