**Answer:**

**Option D, 6 must be factored from **

**Step-by-step explanation:**

**Given : **

**To find : **The given equation in the form

**Solution : **

**Now, we re-write the given equation**

**To covert it into vertex form** where (h,k) represents the vertex.

**First step is to take 6 common from **

**i.e, **

**Now, further step is by completing the square,**

**The required form is **

**Where, **a=6,

**Therefore, Option D is correct, 6 must be factored from **
