Question

Simplify the expression.

(3 + 2i)(4 – i)

Please explain

Answer 1

Do I just foil?

Answer 2

Yes

Answer 3

12-3i+4i-2i^2 Is that my answer? Seems more like complicating than simplifying to me...

Answer 4

or sorry, 2i^2-i+12?

Answer 5

** +i not -i

Answer 6

Final answer -2i^2+i+12? Is that right?

Answer 7

12-3i+8i-2i^2
Final answer is -2i^2+5i+12

Answer 8

wouldn't it be 3i, not 5i? -3i+8i-2i

Answer 9

@mavilia

Answer 10

Where are you getting the -2i from?

Answer 11

Ohh, I'm sorry, nevermind, that's the 2i part of 2i^2, thanks for the help!

Answer 12

No problem!
