To solve the factored quadratic equation \( 0 = -\frac{1}{3}x (x - 6) \), we can set each factor to zero.
-
Set the first factor to zero: \[ -\frac{1}{3}x = 0 \] This simplifies to: \[ x = 0 \]
-
Set the second factor to zero: \[ x - 6 = 0 \] This simplifies to: \[ x = 6 \]
Thus, the solutions for the equation are \( x = 0 \) and \( x = 6 \).
The solution set is \( x = {0, 6} \).
Therefore, the correct answer is: The solution set is \( x = {0, 6} \).
