I have the answer I think, I just want to double check so please don't waste your or my time by making casual homework remarks.

Please be more specific, is it (3(R 6) - 2) or (3(R 6 -2))

(3*V6 - 2)^2, you mean?
(a - b)^2 = a^2 - 2ab + c^2
a = 3*V6, b = 2
so = 9*6 - 2*3*2*V6 + 4 = 54 + 4 - 12V6 = 58 - 12V6.
