"Need to show all work" ... should this be homework or the like?

It should look like this  L= 2(-2)+2(-2)+(-4)/sq. root of
2^2+(-4)^2....IT IS A FRACTION>>>>MUST BE SIMPLIFIED IN RADICAL FORM

L= 2(-2)+2(-4)+(-4)
                      ________________

           sq.root of    2^2+4^2

I assume you mean:

L= [2(-2)+2(-4)+(-4)] / sqrt(2^2+4^2)

If so, start by simplifying.

L= [-4 -8 -4] / sqrt(4 + 16) = -16 / sqrt(20)

I'll leave the final step to you.  Hint, what can you do with sqrt(20)?
