Question 919974
Fombitz beat me to it.  I always like to show graphs, and
the tutors that just show the algebra and no graphs usually 
beat me to it because I have to do the algebra first and
then do the graphs.   Anyway here's the graph:

{{{drawing(400,6400/7,-4,10,-7,25, graph(400,6400/7,-4,10,-7,25,2x^2-4x+5),
graph(400,6400/7,-4,10,-7,25,10+sqrt(24x+25)),

red(line(-1.0417,9.4,-1.0417,10.5)),

graph(400,6400/7,-4,10,-7,25,10-sqrt(24x+25)) )}}}
