Answer:
A.
Step-by-step explanation:
Given function:

To rewrite the equation such that the zeros of the function can be easily identified.
Solution:
In order to find the zeros of the given quadratic function, we will use factorization by splitting up the middle term.
We have:

Splitting
into two term such that the sum of the two terms =
(middle term) and the product of the two terms is =
(product of first and last term)
The terms are
as their sum =
and their product = 
So, we have:

Factoring in pairs of first two terms and last two terms by factoring out their G.C.F.

Since
is a common term, we can factor it out further.
(Answer)
From the above function, we can identify that the zeros of the function are -6 and 2.
