You can put this solution on YOUR website!
I can use logic to find answer
Clearly, if , you have minus factors
on top and bottom and left side is >0
If , left side = 0
If , you have a (+) on top
and a (-) on the bottom, and left side <0
If the bottom = 0, which is infinity
If , top and bottom are (+)/(+)
and left side >0
The solution, then is
