This means that you add a constant term to complete a perfect square. Here is an example (I will use "^" for power):
x^2 + 6x + 5 = 0
Adding 4 to each side gives a perfect square:
x^2 + 6x + 9 = 4
The left side is the square of (x + 3):
(x + 3)^2 = 4
Taking the square root on both sides:
x + 3 = (plus or minus) 2
The constant term, 9, that was required on the left side, was obtained as (6 / 2) ^ 2.
