You can
put this solution on YOUR website!x^2-8x>0
-------
x(x-8) > 0
------------
Draw a number line.
Plot x = 0 and x = 8
-----------------
Check a value in each of the intervals to see where solutions lie.
---
If x = -10 you get -*- > 0 ; true so solutions in (-inf,0)
If x = 5 you get +*- > 0 ; false
If x = 10 you get +*+ > 0 ; true so solutions in (8,+inf)
