Answer:


\huge{\boxed{\sf{ -20i^(2) + 48i - 16}}}

Explanation:

( 8 - 4i ) ( 5i - 2 )

Use the distributive property to multiply each term of the first binomial by each term of the second binomial.


8 ( 5i - 2 ) - 4i ( 5i - 2 )


40i - 16 - 20i^(2) + 8i

Combine like terms.

Like terms are those which have the same base.


- 20i^(2) +40i+ 8i - 16


-20i^(2) + 48i - 16

Hope I helped!

Best regards!
