Which of the following options is a 3rd degree polynomial with exactly 1 real root?
A. F(x) = x2 +9x2 +27x+27
O B. F(X) = x2-94 +27x-27
O C. F(x) = x+3x2 - 9x-27
O D. F(x) = x2 + 3x2 +9x+27

the square root of what number? if you add that, then someone will probably answer the question.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
