Question

Which expressions are equivalent to the given complex number? 45 + 2i A. (2 + 8i) + 2(9 + 6i)(1 - i) B. (9 + 4i) + 2(4 + 7i)(1 - 2i) C. (13 + 4i) + 2(7 + 2i)(2 - i) D. (2 + 8i) + (30 - 6i) E. (9 + 4i) + (36 - 2i) F. (13 + 4i) + (32 - 6i)

Answer 1

Answer:

The correct expression is (9 + 4i) + (36-2i)

Step-by-step explanation:

Here, we want to find the expression that is equal to the given polynomial out of the options

The expression that is equal to 45 + 2i will be

(9 + 4i) + (36-2i)

That will yield;

9 + 36 + 4i-2i

= 45 + 2i
