Find all rational zeros of the polynomial
Rational zeros of the form satisfy the following: p divides the constant coefficient 4; q divides the leading coefficient 1. The choices for p are: , the only choices for q are: .
Thus p/q is one of the following:
Check each of these 6 candidates by plugging the values into the polynomial:
P(1)=-1, P(-1)=-21, P(2)=-12, P(-2)=-28, P(4)=44, P(-4)=204. None of these candidates satisfies P(x)=0; consequently this polynomial does not have any rational roots. All the work was in vain.
