You are very close, but yes there is something wrong

You succeeded in finding the points at which the expression=0, now what we do is plug values in between those points into the expression to see if the inequality is satisified

So we have -5,0, and 5

If you draw a number line and plot these points on it, you will see the number line gets divided into 4 regions namely:

x<-5

-5<x<0

0<x<5

5<x

So we have to test values in each of those regions

So let's try -10 for x<-5,

If x=-10,

So the inequality fails

Now let's try -1 for -5<x<0

If x=-2,

So the inequality holds

Let's try 1 for 0<x<5

If x=1,

So the inequality fails

Let's try 10 for 5<x

If x=10,

So the inequality holds

So the answer is where the inequality holds, namely:

-5<x<0

x>5

When stating your answer you want to say

-5<x<0 or x>5

(A lot of people would say "And" not "or" but this is wrong since x cannot be both <0 and >5)

Also note that it doesn't matter what numbers to choose in the intervals (so choose numbers that are easy to work with)
