Question

Help pleaseeeeee!!!!!!!!!!!!!!

Answer 1

`= 7 + ( - 4x - 3)i`

this is the ans.

Answer 2

None of the option

Explanation:

Given :

(7-3i)+
`(x-2i)^(2) -(4i^(2) +x^(2) )`

(7-3i)+(
`x^(2)`+4
`i^(2)`-4xi)-(-4+
`x^(2)`) Since,
`i^(2) =-1`

(7-3i)+
`x^(2)`-4-4xi +4-
`x^(2)`

7-3i-4xi

7-i(3+4x)

Therefore, None of the option is correct.
