Question

Operations with complex numbers
(8-5i)-(3-9i)

Answer 1

`5+4i`

Explanation:

`(8-5i)-(3-9i)`

In order to subtract we reverse the sign of the each parameter in the parenthesis followed by the negative sign and change the negative sign in front with positive sign.

`(8-5i)+(-3+9i)`

Simplifying it by removing the parenthesis

`8-5i-3+9i\\`

Combining like terms.

`8-3-5i+9i`

`5+4i`
