What number must you add to complete the square of x2 6x17?
To complete the square of x^2 + 6x + 17, you need to add (6/2)^2 = 9 to the expression. This is because half of the coefficient of x is 6/2 = 3, and squaring that gives you 9. So the completed square is x^2 + 6x + 9 + 17 = (x + 3)^2 + 17.
What number must you add to complete the square of x2 minus14 equals 7?
Since there are only terms in x2 and constants, but none in x, completing the square is not an option! x2 - 14 = 7 x2 = 21 and so x2 = sqrt(21)

What number must you add to complete the square of x2 12x -9?
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.

square root -5 minus 14 or - square root -5 minus 14
What number must you add to complete the square of x2 plus 12x equals 40?
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.
