A.(5x + 8i)(x - 8i)
B. (5x + 8i)(5x - 81)
C.(5x + 32i)(5x - 32i)
D.(8x + 5i)(8x - 5i)

Answer 1

Explanation:

Are these the only choices?

A would equal 5x^2-32xi+64

B would equal 25x^2-6561

c would equal 25x^2+1024

D would equal 64x^2+25

If there is an option for (5x+8i)(5x-8i) this would be the answer
