    Smile Eigenvalue (Shouldn't it be simple?)

    Hey there,

    I have a matrix [ [1, 1], [0, s] ]


    I'm supposed to find the eigenvalue (and -vector) of the matrix...

    I end up with something like...

    (1-x)(s-x)-1 = s-x-x*s+x^2-1 = 0

    Okay, so is there any way to make this more simple?

    Because, when i start making vectors, it gets quite unhandy...

    Maybe it is just supposed to be unhandy?


    Uhm, I mean, the above equation is okay, but - when I try to find x it gets really complicated.
    This was by the way the first task in a test without calculators...


    Thanks for taking a peek at it...

    Simon DK.
