Surds A level maths question?
I'm revising for my A levels, and was doing fine until i came across this question. It was to rationalise the denominator, simplifying where possible.

I uploaded a photo of what i did to a very very old twitter account of mine, if anyone could have a look? The answer underlined is what i got, however the one circled is what the actual answer is. Can someone explain to me what i've done wrong and how i would get the right answer?
