hey, not sure how this works on this web site but was just wondering if someone can tell me if i'm doing this right....(adsbygoogle = window.adsbygoogle || []).push({});

find characteristic equation of matrix

A=l 4 0 1 l

l -2 1 0l

l -2 0 1l

i found it to be (L=lambda)...

L^3 - 6L^2 + 11L - 6 = 0

only because i solved the matrix det(LI - A) and found that

=(L-4)[(L-1)(L-1)] -1[0 - (2)(L-1)] ...have i got this right? thanks for the help
