         <description><![CDATA[<pre>Analisando a tabela, levando em consideração que originalmente linha  s5 é uma linha nula, obtém-se o polinômio:

P0= s^7+s^6+2*s^5+2*s^4-s^3-s^2-2*s-2

Na tabela há uma mudança de sinal, tendo assim uma raiz no SPD. Por simetria tem que ter a outra raiz no SPE. Como existem 6 raízes as outras 4 raízes são sobre o eixo 
imaginário.</pre>]]></description>
