I got some definitions that may be useful. But I'm not sure how to start solving the question. Should I substitute the definitions in or what?

You need none of “the definitions” that you have in the second picture. You only need
(ΔA)2 = <(A − <A>)2>
Expand (A − <A>)2 and then apply <> to each term.
