Question

What is the value of the expression (25 + 8)^2 - (8^2 +25^2)?

Answer 1

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.

Answer 2

Step-by-step explanation:

Answer = 2(25)(8) = 400.
