WebProof. Let r be a real root of the polynomial, so that a 0 + a 1r + a 2r 2 +··· + a m−1r m−1 + r m = 0. There are three cases: either r is an integer, or r is irrational, or r = s/t for integers s and t which have no common factors and such that t > 1. We want to eliminate the last case, so assume for the sake of contradiction that it ... WebBelow are six methods - whose variety may prove somewhat instructive. $(0)\ $ By the Parity Root Test, $\rm\: x^2-5\:x-1\:$ has no rational roots since it has odd leading coefficient, odd constant term and odd coefficient sum. $(1)\ $ By the Rational Root Test, the only possible rational roots of $\rm\ x^2 -5\ x - 1\ $ are $\rm\ x = \pm 1\:.$ $(2)\ $ …
