Question

\PLEASE WILL FAN AND MEDAL





A polynomial has been factored, as shown below:

f(x) = (x − 3)(x + 8)(x − 11)

What are the zeros of the polynomial?

3, 8, 11
3, −8, 11
−3, 8, −11
−3, 3, −8, 8, −11, 11

Answer 1

In other words, the question asks when the polynomial f(x)=0
You have f(x) = (x − 3)(x + 8)(x − 11).
Equal that to 0 because that's what the question asks.
0 = (x − 3)(x + 8)(x − 11).

Can you solve it now?

Answer 2

so would it be c

Answer 3

Also, since the polynomial is multiplied, for f(x) to be 0, either one of the factors has to be 0.
So, either
x - 3 = 0
x + 8 = 0, or
x - 11 = 0

Answer 4

OH ok so then it would be a

Answer 5

Yes that's correct

Answer 6

Thank you so much!!

Answer 7

No problem!

Answer 8

no, it's not choice A

Answer 9

oops good catch
