Imaginary Numbers

100

2i(3 + 4i)

Remember i² is equal to -1, which is a sign changer.

Example: -3i²  becomes 3

-8 +6i

200

(- i)(-4 + 5i)

Remember i² is equal to -1, which is a sign changer.

Example: -3i²  becomes 3 

Your answer will look like a + bi

4i + 5

300

(3 - 6i)(3 + 6i)

Remember i² is equal to -1, which is a sign changer.

45

400

(12- i)(11 + 2i)

Remember i² is equal to -1, which is a sign changer. Your answer will have two terms, not three.

134 + 13i

500

(7i - 4i)(-5 - 6i)

Remember i² is equal to -1, which is a sign changer.  Your answer will have two terms, not three.

18 - 15i
