# How do you simplify -7*-4i+4(-1+8i)?

Sep 16, 2016

$- 4 + 60 i$

#### Explanation:

Simplify the multiplication, distribute the bracket and collect like terms.

$- 7 \times - 4 i = 28 i \text{ result of multiplication}$

$\Rightarrow 28 i - 4 + 32 i \text{ distributing bracket}$

$= - 4 + 60 i \text{ collecting like terms}$
