yes

anonymous · Answer

"distribute" the 6, then "distribute" the 3 root 2
and what do you get?

anonymous · Answer

is it 30 + 6 sqrt 2?

anonymous · Answer

expand the bracket u'll get  $$30- 6\sqrt{2} + 15\sqrt{2 - 6}$$  which will give you z answer $$ 24 -9\sqrt{2}$$ or $$8- 3\sqrt{2}$$ when divided by 3
