If the equation 
has undergo completing the square, the answer would be:
**In this example, since 6x is the middle term, what comes to my mind is the polynomial (x+3) because 2ab results into 6x. [from the special products lesson
]
So if the equation is equal to y, then this equation's
The vertex would be on the point (-3, -17)
