Answer:
All three are correct.
Step-by-step explanation:
top left one white
(x + 1 + i)( (x + 1 - i)
(x + 1)^2 - i^2
x^2 + 2x + 1 - i^2
x^2 + 2x + 1 + 1
x^2 + 2x + 2 You have this one correct.
Middle White one
(x - 2)^2 - (2i)^2
x^2 - 4x + 4 - 4*i^2
x^2 - 4x + 4 - 4(-1)
x^2 - 4x + 4 + 4
x^2 - 4x + 8 This one is also correct
Bottom White One
(x + 2i)(x - 2i)
x^2 + 2ix - 2ix - 4i^2
x^2 - 4(i^2)
x^2 - 4(-1)
x^2 + 4 This is correct. But what are all the left overs for? Is there more to the question.
