Question

(4 + 2i) + (-3 – 5i) show your work

Answer 1

Answer:

$\boxed{ \bold{ \huge{\boxed{ \sf{ - 3i + 1}}}}}$

Step-by-step explanation:

$\sf{(4 + 2i) + ( - 3 - 5i)}$

When there is a ( + ) in front of an expression in parentheses, there is no need to change the sign.

That means the expression remains the same.

Just remove the parentheses

$\sf{4 + 2i - 3 - 5i}$

Collect like terms

⇒$\sf{ - 3i + 4 - 3}$

Calculate the difference

⇒$\sf{ - 3i + 1}$

Hope I helped!
