... quadratic polynomials that don’t have roots, x2 + 2 and x2 + 5. That is −x5 + 2x4 − 7x3 + 14x2 − 10x + 20 = −(x − 2)(x2 + 2)(x2 + 5). (We can check the discriminants of x2 + 2 and x2 + 5 to see that these two quadratics don’t have roots.) • 2x4 − 2x3 + 14x2 − 6x + 24 = 2(x2 + 3)(x2 − x + 4). Again, ...
