espandere

(s - 1) (s + 1 + j^{2} π) (s + 1 - j^{2} π)

s^{3} + s^{2} - π^{2} j^{4} s - s + π^{2} j^{4} - 1

Fasi della soluzione

(s - 1) (s + 1 + j^{2} π) (s + 1 - j^{2} π)

= (s - 1) (s + 1 + π j^{2}) (s + 1 - π j^{2})

Espandi

(s - 1) (s + 1 + j^{2} π) : π j^{2} s + s^{2} - π j^{2} - 1

= (π j^{2} s + s^{2} - π j^{2} - 1) (s + 1 - j^{2} π)
