x2+2x+1 = 0
(x+1)(x+1) = 0
x = -1 and also x = -1

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)

You need to add -22.
"The answer" is the number that 'a' must be in order to make the statement true.There are two answers.a = zeroanda = 5
You must add 1

it is 121
You must add (17n + 144).
You must add 36 to complete the square on the left hand side.You must add 36 to complete the square on the left hand side.You must add 36 to complete the square on the left hand side.You must add 36 to complete the square on the left hand side.
You need to add -6
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.

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