The expression (4 + i) - (3 - 5i)(- 2 + 5i) is simplified as (- 15i - 24i). Then the correct option is D.
What is a complex number?
The complex number is the combination of the real part and the imaginary part. Then the complex number is given as
⇒ a+bi
The expression is given below.
(4 + i) - (3 - 5i)(- 2 + 5i)
We know that i² = -1. Then we have
⇒ (4 + i) - [(-6 + 10i + 15i - 25i²]
⇒ (4 + i) - (25i + 25 - 6)
⇒ (4 + i) - (25i + 19)
⇒ 4 + i - 25i - 19
⇒ - 15i - 24i
Then the correct option is D.
