Ok so remember
if a+bi is a root, then a-bi is also a root
since 2i is a root, -2i is also a root
use synthetic division and the fact that when we divide by 2i and -2i, we have to get all real coeficients and end witha zero at the end
I will show the division in the attachment
we find m=8
we then find th resulting equation that is x^2-2x+2=0
quadratic formula
x=

x=1+i or 1-i
m=8 and the other roots are
x=-2i, 1+i, 1-i
We know that standard form = the number that is not expanded.
This equation is expanded so standard form =
2*100=200
9*10=90
6*1=6
3*1/10= 0.3
8*1/100=0.08
200+90=290
290+6=296
296+0.3=296.3
296.3+0.08=296.38
Your answer is 296.38
Hope this helped!
It's 3/2. wat else u need?
