Question

A polynomial has been factored, as shown below:

f(x) = (x − 6)(x + 5)(x − 9)

What are the zeros of the polynomial?

6, −5, 9
6, 5, 9
−6, 5, −9
−6, 6, −5, 5, −9, 9

Answer 1

split the function into three parts and solve

(x-6) = 0
(x+5) = 0
(x-9) = 0

solve for x

Answer 2

A: 6, −5, 9
B: 6, 5, 9
C: −6, 5, −9
D: −6, 6, −5, 5, −9, 9

Answer 3

i dont really get it

Answer 4

(x-6) = 0

what is x?

Answer 5

what do you mean what is x?

Answer 6

what is the value of x?

Answer 7

x = a number, what is that number?

Answer 8

x - 6 = 0
x = ?

Answer 9

-6

Answer 10

nope, try one more time

x - 6 = 0
x = ?

Answer 11

6

Answer 12

i dont really get it sorry

Answer 13

yup!

now we move to the next part:

(x+5) = 0
x = ?

Answer 14

oh yay

Answer 15

-5?

Answer 16

yup!

next part:
(x − 9) = 0
x = ?

Answer 17

9

Answer 18

yup, so our zeros are

x = 6, x = 9, and x = -5

Answer 19

thank you i got it i gave you a medal and ima fan right now
