can anyone help with this???

Answer:
56.25
Step-by-step explanation:
The number you need to add to both sides to complete the square needs to be calculated by doing ([tex]\frac{b}{2}[/tex])². So, in this problem, b= -15.
-15/2 = -7.5, and -7.5² = 56.25. This is the number you will add to complete the square
