Use the Rational Roots Test to Find All Possible Roots x^4+2x^3-5x^2-8x+4=0

$x^{4} + 2 x^{3} - 5 x^{2} - 8 x + 4 = 0$

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.

$p = \pm 1, \pm 2, \pm 4$

$q = \pm 1$

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

$\pm 1, \pm 2, \pm 4$
