Answer:
the equation is
x - 4 = - 9
the number is
-5
Step-by-step explanation:
First, we don't know the number so we represent it with a variable like "x".
then difference simply means subtraction.
" is" simply means = ( equal to)
so the question says that difference of 4 and a number is 9 so we have x - 4 = -9
so now let's solve for x
we group liked terms and make x stand alone.
x = -9 + 4
( +4 because it crossed an equal sign)
x = - 5
we have
x = -5
so we can substitute the -5 into the equation to if its true
from the equation x - 4 = - 9
where we put -5 instead of x
-5 - 4 = - 9
In all cases, if 
has real coefficients, then any complex roots occur in conjugate pairs, so if 
is a root, then so is 
. Also, by the fundamental theorem of algebra, if 
are roots to , then for some constant 
,
1. If 
and 
, then
Given that 
, we have
2.
With 
, we have
The rest are done in the same exact way.
