Now divide both sides by 2 and take the square root, that should get you pretty close to the end.
What do you get?
Apologies for the sloppy LaTex formatting. There should be parentheses around the fractions indicating that both need to be squared.
I think my first issue lies with squaring the fraction. If I could do that I'd be on the way. I don't normally ask to be spoon fed an answer but in this case... Thanks in advance for any all help.
