# How do you simplify (-2-6i)-(4-6i)?

Aug 20, 2016

$\left(- 2 - 6 i\right) - \left(4 - 6 i\right) = - 6$

#### Explanation:

$\left(- 2 - 6 i\right) - \left(4 - 6 i\right)$

= $- 2 - 6 i - 4 + 6 i$ - as we have a minus sign outside we have changed all the signs inside as it is equivalent to multiplying by $- 1$.

Hence above is equivalent to

$- 2 - \cancel{6 i} - 4 + \cancel{6 i}$

= $- 2 - 4$

= $- 6$
