square root -5 minus 14 or - square root -5 minus 14

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.

9

144

-3

Adding 100 completes the square. { I wonder why you want to complete the square when the expression already factors as x(x-20) }.

-7

49/4 or 12.25

x2 + 20x - 39 = 0: Add 61 giving: x2 + 20x + 100 = (x + 10)2

If: x^2 +18x = 29 Then completing the square: (x+9)^2 -81 = 29 or (x+9)^2 = 110

94

You need to add -22.

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.

No it is not. If you want to get a square number you must multiply a number by its self.

x2+12x + 9 = 0. we want the 9 to be a 36. so add 27 to both sides. then (x+6)2-27 = 0.

-17

Put in the - or + values for 4x and 7 is the first step in finding the number needed

x2+6x+17 = (x+3)2+8, so you must add -8.
