Simplify the following expression as much as possible (3+-+2i

- 1 - 23i

Step-by-step explanation:

The expression is

(3+i)-(5-7i)(-2+2i)

The answer to your question can be found in the image attached below.

We need to multiply the terms and add them together

(3+i)  - [ (5)(-2+2i) +(-7i)(-2+2i) ]

= (3+i)  - [ -10 +10i  + 14i -14i^2]

= (3+i)  - [ -10 +10i  + 14i +(14)]

= (3+i)  - [ 4 + 24i ]

= (3+i)  -  4 - 24i

= - 1 - 23i
