Question

The zeros of a quadratic function are located at x=−8 and x=4.

which expression represents a function
a- (x−8)(x−4)
b- (x−8)(x+4)
c- (x+8)(x+4)
d- (x+8)(x−4)

Answer 1

d- (x+8)(x−4)

Explanation:

Hi there!

Factored form of a quadratic equation:
`y=(x-r)(x-s)` where r and s are the zeros of the quadratic

We're given that the zeros are -8 and 4. Plug these into the factored form equation:

`y=(x-(-8))(x-4)\\y=(x+8)(x-4)`

I hope this helps!
