Multiply:( 10 squared plus 2 times 8 squared)(10 squared minus 2 times 8 squared)

-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
