Use the Rational Roots Test to Find All Possible Roots f(x)=-121x^5-x^4+x+11

$f (x) = - 121 x^{5} - x^{4} + x + 11$

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.

$p = \pm 1, \pm 11$

$q = \pm 1, \pm 11, \pm 121$

Step 2

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

$\pm 1, \pm \frac{1}{11}, \pm \frac{1}{121}, \pm 11$
