Draw a graph of :
The area between the roots where the graph goes below the x axis, is the solution. In your case, it seems that there are no roots and therefore, no points such that the graph goes below zero. So, your answer is that the solution is an empty set.

Sorry if the question is answered already but,
You are going to switch +5 over to the other side, substituting +5 with -5
So pretty much .
And is smaller than -5! x might have to be a negative.
Let's try -1.
9 - -9 < -5
or
18 is smaller than -5
NOT!
How about -2?
36 - -18 is smaller than -5
or
54 is smaller than -5
OF COURSE NOT!
So we might have to try a positive for x.
Try 1!
9 - 9 is smaller than -5
or
0 is smaller than -5
NOT!
Try 2!
36 - 18 is smaller than -5
or
18 is smaller than -5
NOT!
What can we do?
Just so we remember,
How about we switch - with +?
So, the only possible answer is that !
EDIT
Actually, x does NOT equal 0! I just figured.
Why don't we try -1 again?
or
NOPE!
No! It has to be an imaginary! (I think)
