Richie is solving the equation x^2 – 12x = 28 by completing the square. What number should he add to both sides of the equation to complete the square? Pleaseee Help

Richie should add the number 36 to both sides.

Step-by-step explanation:

To complete the square, you need to divide b by 2, square it, then add it to both sides. In this case, you'd do this:
