Answer: Choice D.  23-22i

Work Shown:

(-45-22i)+2(5-3i)(5+3i)

(-45-22i)+2(5^2-(3i)^2)

(-45-22i)+2(25-9i^2)

(-45-22i)+2(25-9(-1))

(-45-22i)+2(25+9)

(-45-22i)+2(34)

-45-22i+68

(-45+68)-22i

23-22i

In the second step, I used the difference of squares rule. Keep in mind that i^2 = -1 since i = sqrt(-1).

Answer:

23-22i
