Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! log7(-x) = x^2-14
-------------------------
Write the left side as [log(-x)]/[log(7)].
-----------
Graph the left side and the right side on the same coordinate axes
and find the point(s) of intersection.
---------------------
I get x = -3.8328...
