Sean p(x)=−2x3+x−1 , q(x)=x2−6x+2 y t(x)=x−4
Al operar q(x)−p(x) y p(x)÷t(x) se obtiene:
−2x3+x2−5x−1 y (x−4)(−2x2−8x+31)−123
2x3+x2−7x+3 y (x−4)(−2x2−8x−31)−123

Evaluación de un polinomio
Dado un polinomio arbitrario
p(x) , si reemplazamos la variable por el número real a , decimos que p(a) es el POLINOMIO EVALUADO EN a
Claramente p(a) ∈R
