+f%28x%29+%3E=+g%28x%29+
+5x%5E2+%3E=+23x+-+12+
+5x%5E2+-+23x+%2B+12+%3E=+0+
+%28+5x+-+3+%29%2A%28+x+-+4+%29+=+0+ ( I just guessed at this )
+x+%3E=+4+
and
+x+%3E=+3%2F5+
------------------
+x+%3E=4+ is the solution that works here
This is the case where I have (+)*(+) = (+)
---------------------------------------------
Now (-)*(-) = (+)
+x+%3C=+3%2F5+ is the solution here
---------------------------------------------
+3%2F5+%3E=+x+%3E=+4+
