14-2i
14-4i
2-2i
2-4i

Explanation:

(8-3i)-(6+i)

distribute right side: 8-3i-6-i

Answer 2

2 - 4i

Explanation:

Given expression:

`(8 - 3i) - (6 + i)`

Apply the distributive law: -(a + b) = -a - b

`\implies 8 - 3i - 6 -i`

Collect the real part and imaginary part of the complex number:

`\implies 8 -6- 3i -i`

Simplify:

`\implies 2-4i`
