# How do you simplify (-4+7i)+(-4-7i) and write the complex number in standard form?

$\left(- 4 + 7 i\right) + \left(- 4 - 7 i\right) = - 8 + 0 \cdot i$

#### Explanation:

from the given:$\left(- 4 + 7 i\right) + \left(- 4 - 7 i\right)$

We combine the real parts and we combine the imaginary parts

$\left(- 4 + 7 i\right) + \left(- 4 - 7 i\right) = \left(- 4 - 4\right) + \left(7 i - 7 i\right)$

$\left(- 4 + 7 i\right) + \left(- 4 - 7 i\right) = - 8 + 0 \cdot i$

God bless....I hope the explanation is useful.
