Question

How do you simplify `(3-5 i)+(-2-7i)`?

Answer 1

`1-12i`

Explanation:

Combine like terms. In this scenario, you can add integers with integers, and imaginary numbers with imaginary numbers.

`(color(blue)(3)color(green)(-5i))+(color(blue)(-2)color(green)(-7i))`

`(color(blue)(3+ -2))+(color(green)(-5i+ -7i))`

`color(blue)1color(green)(-12i)`
