Molt bé, les arrels són #a,#b i #c. Cal incloure el coeficient del terme de grau més alt en el producte i saber que els factors de la descomposició són (x - a) on a és l'arrel. <br />

Atenció, les arrels són #a,#b i #c, però els factors de la decomposició són (x <span style="font-weight: bold;">-</span> a) on a és una arrel, per tant, cal vigilar amb el signe del terme independent d'aquests factors. <br />

Atenció, no oblidis que #a és una arrel i per tant també cal considerar el factor corresponent.

Atenció, cal multiplicar pel coeficient del terme de grau més alt per a obtenir la descomposició del polinomi donat.
