You can put this solution on YOUR website!
Look at your terms.
Specifically the second one.
Since it's a sum of positive terms (since x%5E2 is always non-negative), this term is always positive.
The first term is the only one that can be negative.
So when the first term on the left hand is is negative, the whole left hand side is negative.
1-x%3C0
-x%3C-1
x%3E1
