To complete the square for the equation (x^2 + 8x = -3), you need to add ((\frac{8}{2})^2 = 16) to both sides of the equation. This transforms the left side into a perfect square trinomial, resulting in (x^2 + 8x + 16 = 13). Thus, the term you must add is 16.

The constant term - the part without a variable - must be equal to the square of one half the linear term - the number in front of the "x". That is, it must be (12/2)2 = 36.
