Question

How do I solve this?

Multiply the complex numbers below
(-3+2i) (2+i)

Answer 1

you know foil? try that

Answer 2

so (-3 + 2i)(2 + i)

-6 - 3i + 4i + 2i^2

Answer 3

Yes I got that far, but then i get -6-i-2

Answer 4

you can simplify that a little further

Answer 5

-6-i-2 = -8 - i

Answer 6

you mean -8 + i
(not -8 -i)

Answer 7

oops, that's right! -8 + i. thanks @phi

Answer 8

-3i+4i=1i
i^2=-1

Answer 9

oh, I was stuck at that part, not sure how to get the answer

Answer 10
