Factor.

Rewrite $9 x^{3} + 21 x^{2} - 17 x + 3$ in a factored form.

Factor $9 x^{3} + 21 x^{2} - 17 x + 3$ using the rational roots test.

If a polynomial function has integer coefficients, then every rational zero will have the form $\frac{p}{q}$ where $p$ is a factor of the constant and $q$ is a factor of the leading coefficient.

$p = \pm 1, \pm 3 q = \pm 1, \pm 9, \pm 3$

Find every combination of $\pm \frac{p}{q}$ . These are the possible roots of the polynomial function.

$\pm 1, \pm 0.\overline{1}, \pm 0.\overline{3}, \pm 3$

Substitute $0.\overline{3}$ and simplify the expression. In this case, the expression is equal to $0$ so $0.\overline{3}$ is a root of the polynomial.

Substitute $0.\overline{3}$ into the polynomial.

$9 \cdot {0.\overline{3}}^{3} + 21 \cdot {0.\overline{3}}^{2} - 17 \cdot 0.\overline{3} + 3$

$0.\overline{3} + 21 \cdot {0.\overline{3}}^{2} - 17 \cdot 0.\overline{3} + 3$

Raise $0.\overline{3}$ to the power of $2$ .

$0.\overline{3} + 21 \cdot 0.\overline{1} - 17 \cdot 0.\overline{3} + 3$

Multiply $21$ by $0.\overline{1}$ .

$0.\overline{3} + 2.\overline{3} - 17 \cdot 0.\overline{3} + 3$

Add $0.\overline{3}$ and $2.\overline{3}$ .

$2.\overline{6} - 17 \cdot 0.\overline{3} + 3$

Subtract $5.\overline{6}$ from $2.\overline{6}$ .

$- 3 + 3$

Add $- 3$ and $3$ .

$0$

Since $0.\overline{3}$ is a known root, divide the polynomial by $3 x - 1$ to find the quotient polynomial. This polynomial can then be used to find the remaining roots.
