Hello, I’ve noticed that the answer for Question 1 in the graded quiz is incorrect.
I spent hours trying to debug my answer after I got it “wrong” in the quiz, but Wolfram alpha gives the same solution that I found… can you please review?
Thanks.
Hi! Can you please share your line of thought? The answer looks coorect. Furthermore, I have just input the matrix to Wolfamalpha and it returned the same characteristic polynomial as the answer in quiz expects.
Thanks,
Lucas
My mistake - it was an issue with the power of the coefficient on my end. Thanks!
