10 squared minus 2 times 8 squared= -28
228+ -28= 200
Answer:
-6384
Step-by-step explanation:
= (10^2 + 2 x 8^2)(10^2-2 x 8^2)
= (100 + 2 x 8^2) (10^2-2 x 8^2)
= (100 + 2 x 64) (10^2-2 x 8^2)
= (100 + 128) (10^2-2 x 8^2)
= 228 (10^2-2 x 8^2)
= 228 (100 - 2 x 64)
= 228 (100 - 128)
= 228 (-28)
= -6384
