Question

What are the zeros of the polynomial function?​

Answer 1

8 and 4

Explanation:

if we factor the trinomial, we would get (x - 8) and (x - 4)

to find the zeros for the first one, we would have to add 8 to both sides, and check. So if x = 8, then 8 - 8 = 0, which is true.

Then we do the same for the 4. Substitute 4 for x, and we get 4 - 4 = 0.

Answer 2

The zeros are 4,12

Explanation:

To find the zeros, we set the function equal to zero

0=x^2 -16x+48

What two numbers multiply together to give us 48 and add together to give us -16

-4*-12 = 48

-4+-12 = -16

0= (x-4) (x-12)

Using the zero product property

x-4 = 0 x-12 = 0

x=4 x=12

The zeros are 4,12
