For roots r1 and r2, the factors are (x-r1)(x-r2)
given
r1 and r2 arer 5+i√2 and 5-i√2
(x-(5+i√2))(x-(5-i√2))=
(x-5-i√2)(x-5+i√2)=
remember that i²=-1
x²-10x+27
One expression you can do, is to simply simplify the expression,
We can deistribute the 3
6n+9+9
You can then simplify further:
6n+18
Once we have the simplified expression, you can then expnd it in different ways for example:
3(2n+6)
Hope these helped!
It can increase the field because of the loops around the electromagnet like a conductor which can amplify the magnetic field making it go further

Answer:
y = x + 7
Step-by-step explanation:
The line has a "rise" of 1 grid square for each "run" of 1 grid square to the right. (It passes through successive grid intersections.) This means it has a slope of ...
m = slope = "rise"/"run" = 1/1
m = 1
The line crosses the y-axis at y = 7, so the y-intercept is ...
b = 7
Then the slope-intercept form equation is ...
y = mx + b
y = x + 7
