Answer:
After expanding the polynomial 
we get 
Step-by-step explanation:
We need to expand the polynomial
Multiply the terms:
So, after expanding the polynomial we get
Answer:
we need more details :(
Step-by-step explanation:
What do the places mean? I’d say the signs are negative since both values are (-3) and (-5), but i don’t know what you mean by placed - if they were placed in a number line, it would go 3 and 5 values left or down.
The modulus of complex number can be computed with this equation:
|z|=sqrt(Re(z)^2+Im(z)^2)
z = -2-6i
Re(z)=-2, so Re(z)^2=4
Im(z)=-6, so Im(z)^2=36
|z|=sqrt(36+4)=sqrt(40)=6.3
