Answer:
The correct option is A.
Step-by-step explanation:
The given expression is
[tex]-2i(4-i)[/tex]
We need to find the simplified form of the given expression.
Using distributive property we get
[tex]-2i(4)-2i(-i)[/tex]
[tex]-8i+2i^2[/tex]
We know that [tex]i^2=-1[/tex]. Using this fact we get
[tex]-8i+2(-1)[/tex]
[tex]-8i-2[/tex]
Write the above expression as a+ib.
[tex]-2-8i[/tex]
Therefore the correct option is A.
