B)

Step-by-step explanation:

the equation is:

we have an equation of the form

where

and we must complete the square to obtain a perfect square binomial,

we must add and substract the following:

which is:

and then the equation becomes:

where the terms are the components of the perfect square binomial:

and thus, the equation now is:

the answer is: B)
