Question

Can anyone help me with this equation? I need to show the work

Simplify the expression (5-4i) (-3 - 4i) – (10-3i)

Answer 1

`-5i-41`

Explanation:

Hi there!

`(5-4i) (-3 - 4i) - (10-3i)`

Open up the parentheses

`= -15-20i+12i+16i^2- 10+3i`

i² = -1

`= -15-20i+12i-16- 10+3i`

Combine like terms

`= -5i-41`

I hope this helps!
