(ASAP PLEASE) so I know the answer is 8 root three but I always come to a dead end up while working it out.

(2 + √3)^2 - (2 - √3)^2 (expand the expressions)

4 + 4√3 + 3 - (4 - 4√3 + 3) (calculate)

4 + 4√3 + 3 - (7 - 4√3) (remove the parantheses)

4 + 4√3 + 3 - 7 + 4√3 (calculate and collect like terms)

0 + 8√3 (remove 0)

8√3
