Using the imaginary unit i, simplify the expression: (6i - 2) * (3i + 1)

• -12 + 18

• -12 + 18i

• 12 - 18i

• -12 - 18i

Using the imaginary unit i, simplify the expression: (5i + 2) * (4i - 3)

• 3 + 6i

• -8 - 15i

• -14 + 17i

• 10 - 7i

Using the imaginary unit i, simplify the expression: (7i - 4) * (2i + 5)

• 35i - 2

• 38i - 3

• 14i + 1

• 10i - 20

• 7 - 6i

• 11 + 2i

• 15 - 8i

• 23 + 14i

(-3- i )(6 - i )

• -21-7i

• -19-3i

• -15-5i

• -17-9i

(5 - i )( 5 - i )

• 15-8i

• 36

• 24+10i

• 24-10i

(7-5i)(7+5i)

• 74

• 75

• 74-1

(5 - i )( 5 + i )

• 15-8i
