Question

How do I Simplify (6 — 4i) — (і +5)?

Answer 1

To simplify (6 - 4i) - (і +5), you have to apply associative property.

First step is to remove the parenthesis, then you have:

$6\text{ - 4i - i + 5}$

Now collect like terms:

$\begin{gathered} 6\text{ + 5 - 4i - i} \\ =\text{ 11 - 5i} \end{gathered}$

ANSWER:

$11\text{ - 5i}$
