This means that the … WebbOne can now use the Rational Root Theorem to show that no such b2Q exists. b= d. If b= d, then b= 24. If b= 4, we have b+ac+d= 8 a = 20 which gives a2 = 28; no such a2Q exists. If b= 4, we have b+ac+d= 8 a2 = 220 which gives a = 12; again, no such a2Q exists. We conclude that f(x) is irreducible. Hence, it is the minimal polynomial of over Q.
