phi · Answer

when you see 1+ sqrt(3) in the bottom
think  "multiply by the conjugate"  which means  
multiply by (1- sqrt(3))

you should multiply top and bottom by (1- sqrt(3))
use FOIL

anonymous · Answer

I did and somehow I wasn't able to get the answer can you draw on the board?

phi · Answer

what do you get for
(1+sqrt(3))(1- sqrt(3)) ?

FOIL means  First, outer, inner, last
where first means the 1's,  outer means the 1 on the left and the -sqrt(3) on the right,
and so on
