    Answer:

    Step-by-step 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:

    3+5i

    Step-by-step 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 🙂
