Question

Write -2i + (9 − 3i) − (6 − 10i) as a complex number in standard form.

Answer 1

Explanation:

b/c you can treat the real and imaginary parts separate, you can just add up real and imaginary like terms of expressions

9-6=3

-2i-3i+10i =5i

3+5i :)

Answer 2

3+5i

Explanation:

-2i+(9-3i)-(6-10i)

expand parenthesis

-2i+9-3i-6+10i

imagine that the i takes place of an x, so you can just add like terms

3+5i

Hope that helps :)
