Step 1.2.2.1

Factor $x$ out of $x^{3}$ .

$\frac{x a}{x \cdot x^{2}}$

Step 1.2.2.2

Cancel the common factor.

$\frac{x a}{x \cdot x^{2}}$

Step 1.2.2.3

Rewrite the expression.

$\frac{a}{x^{2}}$

Step 2

The Rational Roots Test requires the polynomial to have integer coefficients. Since $\frac{a}{x^{2}}$ does not, the Rational Roots Test cannot be used.
