Hey can you me posted picture of question

The correct answer  for the problem shown in the figure atttached is the last option (option D), which is shown below:

 D. (-3x+6i)(x+2i)
 It is impotant to know that if you want to verify that the option D. (-3x+6i)(x+2i) is the correct answer, you can apply the distributive property to (-3x+6i)(x+2i). 
 Therefore, when you apply the distributive property, you obtain that the result is:
 -3x²-12

 Which is correct

 Therefore, you can be sure that the correct answer is the option D. (-3x+6i)(x+2i).
