Answer:

Step-by-step explanation:
In this question we are required to rewrite the given function by using completing the square method.
Completing the square method requires that our given equation can be written in form: 
SO, we have to transform our equation according to above format.
Since our equation is
, we will transform it into
because the middle term of given equation has + sign.

We have introduced (1/2)^2 on both sides of the equation to gain the required form.

Our answer is
