Answer:
The zeros of the given polynomial function f(x) are -3,0,-4
Step-by-step explanation:
Given polynomial is 
To find the zeros of the given polynomial:
First equate the polynomial function f(x) to zero
That is 
By synthetic division we can solve it
-3_| 3 21 36 0
0 -9 -36 0
_____________________
3 12 0 0
Therefore x+3 is a factor
That is x=-3 is a zero


3x=0 or x+4=0
Therefore x=0 or x=-4
Therefore the zeros are -3,0,-4
The sum (addition) of -2 and 3 times (3 ·) a number (n)
-2 + 3n
That is one half also 1/2 if this was not what u where looking for then just tell me
You can always try 4 divide 2/3=
and what ever you get is your answer
4 divide 2/3= 0.66666666666
Your going to have to round
Hope this helps
We will be able to build our expression as follows
6 + 8x
When we plug in x=5
6 + 8(5)
We will first do 8*5 = 40
6 + 40
46
