Step-by-step explanation:
To complete the square, begin by separating the x terms from the constants by moving the constants to the other side of the equals sign:
Now we can complete the square. Take half the linear term, square it, and add it to both sides. Our linear term is 12. Half of 12 is 6, and 6 squared is 36. We add 36 to both sides:
In the process of completing the square we created a perfect square binomial. I will state that binomial along with simplifying the right side of the equation:
That's the form you need it in. I have a feeling that the B choice you left out is the one you want!
