# How do you combine (8-8i) - (6-4i) ?

Nov 20, 2015

Combine the Real and Imaginary components independently to get
$\left(2 - 4 i\right)$

#### Explanation:

$\left(\textcolor{red}{8} - \textcolor{b l u e}{8 i}\right) - \left(\textcolor{red}{6} \textcolor{b l u e}{- 4 i}\right)$

$\textcolor{red}{\text{Real components") color(white)("X}} \textcolor{red}{8 - 6 = 2}$

$\textcolor{b l u e}{\text{Imaginary components")color(white)("X}} \textcolor{b l u e}{- 8 i - \left(- 4 i\right) = - 4 i}$
