Question

m

Answer 1

No. Use FOIL...we get

1 -3i + 7i - 6i^2

Since i^2 = -1, we get

1 -3i + 10i +6

= 7 + 7i

Answer 2

First line should read 1 - 3i + 10i - 6i^2

Answer 3

You get 7 + 7i

Answer 10

Simplifying
(1 + 2i)(5 + -3i)

Multiply (1 + 2i) * (5 + -3i)
(1(5 + -3i) + 2i * (5 + -3i))
((5 * 1 + -3i * 1) + 2i * (5 + -3i))
((5 + -3i) + 2i * (5 + -3i))
(5 + -3i + (5 * 2i + -3i * 2i))
(5 + -3i + (10i + -6i2))

Combine like terms: -3i + 10i = 7i
(5 + 7i + -6i2)

Answer 11

yes :)
