You can put this solution on YOUR website!
let the number be x, then:

+x-x%5E3%3E2+
+x-x%5E3-2%3E0+
+x%5E3-x%2B2%3E0+

So first find where +x%5E3-x%2B2=0+. The solution to this is not straight forward and i don't have time to write it all down here, sorry. You can re-submit or ask your teacher, sorry.

cheers
