Hello, I am sorry for removing the template but it is not an actual problem that I need help with. Well it is, but it should be pretty quick and straight forward.(adsbygoogle = window.adsbygoogle || []).push({});

The problem is located here: http://www.cdli.ca/courses/math3103/unit05_org01_ilo04/images/3-less9.gif [Broken]

(It's a bit difficult to type out.)

I'm having difficulty with only 1 step that I need straightened out.

On the second last line, where did the 1/2 outside of the square root function come from? And Why does it appear there? I am thinking the 1/2 just got moved out of it, because it was under x+3.

Please help, thank you so much.
