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.

a_110 = -7 + 10(110 - 1) = 1083

d = -27 - (-22) = -5

second -7 - 5=  -12
