[線代] 兩題行列式

[mqazz1 (無法顯示)]

1. suppose A in R^(3*3)

and det(xI - A) = x^3 - x^2 + 3x - 2,

then det(xI - A^2) = ?


2.  [2^0 2^1 2^2 2^3 2^4 2^5]
    [2^1 2^0 2^1 2^2 2^3 2^4]
T = [2^2 2^1 2^0 2^1 2^2 2^3]   //2^3 表 2的3次方=8
    [2^3 2^2 2^1 2^0 2^1 2^2]
    [2^4 2^3 2^2 2^1 2^0 2^1]
    [2^5 2^4 2^3 2^2 2^1 2^0]

det(T) = ?


請問這兩題怎麼解呢?

謝謝
