Answer:
The coefficient is
Step-by-step explanation:
From the question we are told that
Generally the coefficient of determination is mathematically represented as
substituting values
D
Given
(- 4 + 5i)(5 + 2i) ← expand factors using FOIL
= - 20 - 8i + 25i + 10i² ← i² = - 1
= - 20 + 17i - 10
= - 30 + 17i
