simplifying in the form a+b?c ??

I've just been given a question:

Simplify the following in the form a + b?c where a, b and c are intergers:

a) (3+?2)^2

b) (2?3+4)(2-?3)

c) 2/?3-1

No need to actually give me the answers, just tell me how to simplify them

Must have been sleeping/generally not paying attention when I was supposed to learn these Or it could be that these questions were thrown in just to be evil and I was never taught them at all!

(probably the former )

Thanks in advance.

For a and b, just expand the brackets and collect like terms. c is already in that form ( or it could be written -1+2rt3)

No, the sqr ia at the bottom in c

2/?3-1 is in fact -1 + 2/3 sqr(3)

No, the sqr ia at the bottom in c

2/?3-1 is in fact -1 + 2/3 sqr(3)

No.

$\frac{2}{\sqrt{3}-1} \neq -1 + \frac{2}{3} \sqrt{3}$

errmm excuse me but there were no brackets in the original stem (c). It showed as $\frac{2}{\sqrt{3}}-1$
