Answer:
None of the option
Step-by-step explanation:
Given :
(7-3i)+[tex](x-2i)^{2} -(4i^{2} +x^{2} )[/tex]
(7-3i)+([tex]x^{2}[/tex]+4[tex]i^{2}[/tex]-4xi)-(-4+[tex]x^{2}[/tex]) Since, [tex]i^{2} =-1[/tex]
(7-3i)+[tex]x^{2}[/tex]-4-4xi +4-[tex]x^{2}[/tex]
7-3i-4xi
7-i(3+4x)
Therefore, None of the option is correct.
