x2 + 5x + 6¼ = (x + 2½)2 and, hence, is a perfect square.
As the co-efficient of x2 (the first term) is 1, you can safely follow this rule:
Add the square of half the co-efficient in the second term, in order to complete the square.
In this case, you take half of 5 (which is 2½) and, then, square it. This gives you your 6¼.

The idea is to take half the linear part (12, in this case), then square it. The constant part must be equal to this result.

What number must be added to the polynomial to complete the square x2 - 20x?
Adding 100 completes the square. { I wonder why you want to complete the square when the expression already factors as x(x-20) }.

What must be added to 452664 to make it a perfect square?
Sqrt of 453664 is 672 and a bit.So next square is 673 squared, ie 452929, so 265 must be added.
What number can be added to complete the square x2 plus 10x equals 14?
9 needs to be added to complete the square. When squaring (x + n), the result is x2 + 2nx + n2. We have +10x, so n must be 10/2 = 5. Thus: (x + 5)2 = x2 +10x + 25 = x2 +10x + 14 + 9 So 9 needs to be added to complete the square, giving: x2 +10x + 14 = (x + 5)2 - 9
