Use the Rational Roots Test to Find All Possible Roots 2x^6-10x^5-23x^4+80x^3+28x^2-20x+9

$2 x^{6} - 10 x^{5} - 23 x^{4} + 80 x^{3} + 28 x^{2} - 20 x + 9$

Step 1

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.

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

$q = \pm 1, \pm 2$

Step 2

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

$\pm 1, \pm \frac{1}{2}, \pm 3, \pm \frac{3}{2}, \pm 9, \pm \frac{9}{2}$
