Question

Simplify the following product of complex numbers.

(8 + i) · (-4 – 3i)

Answer 1

-32-24i-4i-3i^2
-32-28i+3
-29-28i

Answer 2

(8 + i) · (-4 – 3i)
=8(-4) + (-3i)(8)+(i)(-4)+(i)(-3i)
=-32-24i-4i+3
=-29-28i

Answer 3

but i^2=-1 so the answer is -29-(-28)=-1

Answer 4

no, there is only one i in -29-28i
(-1)=i^2
-29-28i=-29+28(i^2)(i) but not -29-(-28)=-1

Answer 5

sorry
