(2 - 4 i) (- 5 - 3 i)

Solution

- 22 + 14 i

Solution steps

(2 - 4 i) (- 5 - 3 i)

Apply complex arithmetic rule:

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

= (2 (- 5) - (- 4) (- 3)) + (2 (- 3) - 4 (- 5)) i

Simplify

(2 (- 5) - (- 4) (- 3)) + (2 (- 3) - 4 (- 5)) i : - 22 + 14 i

= - 22 + 14 i
