A polynomial has real coeffients
a polynomial with roots b and c and d can be.factored into the form
f(x)=a(x-b)(x-c)(x-c)
and each of those terms can be raised to any positive power
if it has real coeffients and.one of the roots is a+bi (compex number) then a-bi is also root
ok, so since 2+3i is a root, 2-3i is also a root
the function can bex
f(x)=a(x-2)(x-1)(x-(2+3i))(x-(2-3i))
where a can be any real number except 0
expand it yourself to get the polynomial because it's hard to type nyubers on mobile
note that i=√-1 so i^2=-1

Answer:
Step-by-step explanation:
Answer: The length of the third side is greater than 4 ft and less than 20 ft.
Step-by-step explanation: Given that two sides of a triangle have lengths 8 ft and 12 ft.
We are to describe the possible lengths of the third side.
Let x ft be the length of the third side of the triangle.
We know that
the sum of the lengths of any two sides of a triangle is always greater than the third side.
So, we must have
Also,
and
From inequalities (i), (ii) and (iii), we get
Thus, the length of the third side is greater than 4 ft and less than 20 ft.
I'm not sure about your topic! like -2>= could be -1,0,1,2,3,4,5,6,....
I am going to go with choice A
