Answer:
-1/4 and 1/4
Explanation:
We need to find 2 numbers with a difference of 1/2 and equal squares. Two different numbers will have equal squares only if they are opposites. That means that they are the same distance from 0 too. So each number have to be 1/4 away from 0. Thus, the answers are 1/4 and -1/4.
