Question

question #3 determine the domain restriction(s) or excluded values of the following rational expression: $\frac{4x + 8}{x^{2}-3x}$
$x = 0;x=-3;x = 2$
$x = 0;x = 3$
$x = 0;x=-3$
$x = 0;x = 3;x=-2$

Explanation:

Step1: Set denominator not equal to 0

$x^{2}-3x
eq0$

Step2: Factor the denominator

$x(x - 3)
eq0$

Step3: Solve for x

$x
eq0$ and $x
eq3$

Answer:

$x = 0;x = 3$
