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

Answer:

$-5i-41$

Step-by-step 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!
