Question

solve $x^2 - 16x + 60 = -12$ by completing the steps. first, subtract \boxed{} from each side of the equation. done

Explanation:

Step1: Rearrange constant terms

To isolate the x-terms, we need to move the constant 60 to the right side. Subtract 60 from both sides:
$x^2 - 16x + 60 - 60 = -12 - 60$

Step2: Simplify both sides

Calculate the right-hand side result:
$x^2 - 16x = -72$

(Note: The first blank in the problem asks for the value subtracted from each side, which is the constant term on the left, 60.)

Answer:

60
