If we have:

Then, the first option must be matched with -20. That is:


(2+5i)^2-20i+1=-20_{}_{}

In this question, we need to be careful with the value of i^2 = -1, and we also need to expand the quadratics in every given expression.

2. For the next expression, we have:


(4+i)(-4+i)+17=0

3. For the next expression, we have:


(3+2i)^2-(2+3i)^2=10

4. The result for the next expression is:


2i(5+4i)-5(3+2i)=-23

5. The result for the next expression is:


(-2i)^4+(3i)^3+(27i)=16
