(- 2 - 2 i) (- 4 + 6 i)

Solution

20 - 4 i

Solution steps

(- 2 - 2 i) (- 4 + 6 i)

Apply complex arithmetic rule:

(a + bi) (c + d i) = (a c - b d) + (a d + b c) i

= (- 2 (- 4) - (- 2) \cdot 6) + (- 2 \cdot 6 - 2 (- 4)) i

Simplify

(- 2 (- 4) - (- 2) \cdot 6) + (- 2 \cdot 6 - 2 (- 4)) i : 20 - 4 i

= 20 - 4 i
