Answer
$C$
Work Step by Step
To solve this equation, set each factor equal to $0$ and solve for $x$:
First factor:
$2x - 4 = 0$
Add $4$ to each side of the equation:
$2x = 4$
Divide each side of the equation by $2$:
$x = 2$
Second factor:
$x + 6 = 0$
Subtract $6$ from each side of the equation:
$x = -6$
The solution set is ${2, -6}$.
This corresponds to answer option $C$.
