Karena Itu adalah matriks identitas maka
I = I^2 = I^3 = I^4 = dan seterusnya
P = (-1 ... 0) = -1 (1 ... 0) = -1 I
...... (0 ... -1) ...... (0 ... 1)

- p^4 + 2P^3 - 3P^2 + 4I
= - (-1 I)^4 + 2 (-1 I)^3 - 3 (-1 I)^2 + 4I
= -1 (-1)^4 (I)^4 + 2 (-1)^3 (I)^3 - 3 (-1)^2 (I)^2 + 4I
= -1 I - 2I - 3I + 4I
= -2 I
= 2 . -1 I
= 2 P
