Multiplying complex numbers

(3+4i)(-8-i)

• -5+3i

• -24-4i

• -24-4i²

• -20

• -20-36i

Simplify the expression completely: $-3i\left(-1+4i\right)$  

•  $12+3i$  

•  $3i-12i^2$  

•  $-12-3i$  

The expression $(-3+2i)(1-4i)$ is equivalent to:

•  $-2-2i$  

•  $5+14i$  

•  $-11-10i$  

•  $-3-8i$  

• -1

• 1

• i

• -i
