You can put this solution on YOUR website!
+%28x-17%29+%2F+%28%28x-20%29%2A%28x%2B9%29%29+%3C+0+
I can use logic to find answer
Clearly, if +x%3C17, you have minus factors
on top and bottom and left side is >0
If x=17, left side = 0
If +17%3Cx%3C20, you have a (+) on top
and a (-) on the bottom, and left side <0
If x=20 the bottom = 0, which is infinity
If x+%3E20, top and bottom are (+)/(+)
and left side >0
The solution, then is +17%3Cx%3C20+
