<u>Answer:</u>
The factorization of given expression is (x + 9i)(x – 9i) and option d is correct.
<u>Solution:</u>
Given, expression is
We have to factor it in the complex numbers.
Let us check options to find answer.
<em><u>A) (x – 9)(x – 9) </u></em>
(x – 9)( x – 9)
So, this is not correct answer.
<u><em>B) (x + 9)(x + 9) </em></u>
So, this is not correct answer.
<u><em>C) (x + 9i)(x + 9i) </em></u>
So, this is not correct answer.
<u><em>D) (x + 9i)(x - 9i) </em></u>
Thus option D is correct
Hence, the factorization of given expression is (x + 9i)(x – 9i). and option d is correct.
