Hello ive worked these out in my notebook but havbe no way to check if they are correct or not here they are

a) ( √2 - √8)² = 2

b) ( -1/3√3 - 1 )²

c) ( √3 + √12 ) ²

I know I got to do the perfect square trinomial

a²+ 2ab + b² I did that just would like the working out of it and answers in case I got them wrong

ps , im not skipping on my homewrok just got a test on thurdays and want to see if im ok since i go t no more math classes till then thats why I ask for the work out of it

THANKSS
