I've followed and understood this small example of calculating jordan forms all the way to the last line where they say "Therefore, the jordan form is...". When they say "therefore", it's NEVER obvious(adsbygoogle = window.adsbygoogle || []).push({});

Anyway, I get why the diagonal entries are -1. And that a minimal polynomial (t+1)^2 means I have two Jordan blocks with dimensions 1 and 2. But why is (3,2) in the final answer one? Or perhaps I should ask: how do you know what "non-diagonal" numbers to put where, when you get to this point of the calculation. Thanks in advance!
