Answer 1

distribute it.

Answer 2

idk how man

Answer 3

a(b-c) = ab-ac

Answer 4

use that ^

Answer 5

i^2 = -1

Answer 6

no i know that, but i don't know how to do it with imaginaries

Answer 7

it's the same thing..

Answer 8

but when i is multiplied i it becomes -1

Answer 9

what is 3i*-4?

Answer 10

\[i = \sqrt{-1} , i^2 = \sqrt{-1} * \sqrt{-1} = -1\]

Answer 11

im sorry im not sure i get it

Answer 12

3i*-4 = -12i

Answer 13

3i * -6i = -18i^2
i^2 = -1 so -18i^2 = -18 * -1 =18

Answer 14

ans: 18-12i

Answer 15

same old distribution you are used to. the imaginary numbers throws a curve ball at you, but not for long

Answer 16

oh ok i think i grasp it now, so i^2 is just -1 then,
