Would you help me with this:

Let A is inC^4.A =( 0 0 0 -1

1 0 0 2

0 1 0 -2

0 0 1 2)

(i)Determine the minimal characteristic polynomials ofA.

(ii) Determine the Jordan form ofA.

(iii) Construct a basisBof C^4such that [T_A]_B is in Jordan form , where T_A is the linear map T_A: -> C4 : X -> AX.

Thank you!
