Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website! Start with the given expression. Take half of the coefficient to get . In other words, . Now square to get . In other words,Because (a + 1) 2 = a, a + 1 is the unique solution of the quadratic equation x 2 + a = 0. On the other hand, the polynomial x 2 + ax + 1 is irreducible over F 4, but it splits over F 16, where it has the two roots ab and ab + a, where b is a root of x 2 + x + a in F 16. This is a special case of Artin–Schreier theory. See alsoTwo numbers r and s sum up to -3 exactly when the average of the two numbers is \frac{1}{2}*-3 = -\frac{3}{2}.
