Answer: 400
(25 + 8)^2 − (8^2 + 25^2)
= (33)^2 − (64 + 625)
= 1089 − 689
= 400
Remember:
•follow the BEDMAS or PEDMAS rule
•always go from left to right
Note: the steps could’ve been broken down further but since working on the right side won’t change the left side, in this case, it was just a faster way of showing the results.
