Answer:
Step-by-step explanation:



Hope it helps!
0 because you can divide them ie 0 is divisible with 5 and 10

Notice that equality holds when either

or

, so these should be included in the solution set.
Now, since the coefficient of the leading term is positive, we know the parabola opens upward, which means we know that

when

and

, and that

when

.
So the solution set is the interval

.
