Solve the radical equation, and check all proposed solutions.
-$$x ^ { 3 } - 8 x ^ { 2 } + 15 x = 0$$
A) $\{ 0,5,3 \}$
B) $\{ 5,3 \}$
C) $\{ 0 , - 5 , - 3 \}$
D) $\{ - 5 , - 3 \}$

Question

Quizplus · Accepted Answer

The equation can be factored as $x(x^2 - 8x + 15) = 0$, which further factors to $x(x-5)(x-3) = 0$. The solutions are $x = 0$, $x = 5$, and $x = 3$.
