Let C be a 2 × 2 matrix such that x is an eigenvalue of C with multiplicity two(adsbygoogle = window.adsbygoogle || []).push({});

and dimNul(C − xI) = 1.

Prove that C = P |x 1|P^−1

|0 x|

for some invertible 2 × 2

matrix P.

I'm not sure where to start

EDIT

|x 1|

|0 x| is the matrix I don't know why it's not posting the way I want it
