simplify

(- 4 - 4 i) \cdot (- 5 - 3 i)

Solution

8 + 32 i

Solution steps

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

Apply complex arithmetic rule:

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

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

Simplify

(- 4 (- 5) - (- 4) (- 3)) + (- 4 (- 3) - 4 (- 5)) i : 8 + 32 i

= 8 + 32 i
