The polynomial is given to be:


x^4+2x^3-8x^2+16x-32

The Rational Roots Test (also known as Rational Zeros Theorem) allows us to find all possible rational roots of a polynomial. Suppose we have some polynomial P(x) with integer coefficients and a nonzero constant term. If p represents the factors of constant term and q represents the factors of the leading coefficient, the possible rational roots will be:


\Rightarrow(p)/(q)

From the polynomial given, the constant term is -32 and the leading coefficient is 1.

Therefore, the factors of the constant will be:


p=1,2,4,8,16,32

and the factors of the leading coefficient will be:


q=1

Hence, the possible rational roots will be:


\begin{gathered} \pm(p)/(q)=\pm(1)/(1),\pm(2)/(1),\pm(4)/(1),\pm(8)/(1),\pm(16)/(1),\pm(32)/(1) \\ \therefore \\ \pm(p)/(q)=\pm1,\pm2,\pm4,\pm8,\pm16,\pm32 \end{gathered}
