Use the Rational Roots Test to Find All Possible Roots x^3+3=5

$x^{3} + 3 = 5$

Step 1

Subtract $5$ from both sides of the equation.

$x^{3} + 3 - 5 = 0$

Step 2

Subtract $5$ from $3$ .

$x^{3} - 2 = 0$

Step 3

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.

$p = \pm 1, \pm 2$

$q = \pm 1$

Step 4

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

$\pm 1, \pm 2$
