Carlo is trying to factor the polynomial p(x) = x4 – 4x3 – 4x2 + 24x –9 to determine all of its zeros. He discovers one
factor by making a guess and dividing the polynomial, so he has p(x) = (x - 3)(x³ – x² - 7x + 3). Now he is trying to
factor x3 - x2-7x + 3, so he tries dividing it by (x + 3), then by (x + 1), and finally by (x – 1), but none works without
a remainder. Then Teo comes by and says, "You should look at the graph."
