I haven't got very far, but I've so far got the fact that you need two brackets and from there, I'm stufffed....
(x+ ?) (x- ?)
That's it, i think its gonna have to be a fraction or something... I'll give it a try... Sorry i couldn't be mroe help... <3

What equations is the result of completing the square on x2 - 6x - 9 0?
Without an equality sign the expression given can't be considered to be an equation.
Solve by completing the square x2 14x -24?
the problem is not proper to slove. I just want to suggest to follow the related link that explains the concept of completing the square clearly.
Can you solve by completing the square x2 plus 10x plus 220?
No because the discriminant of the given quadratic expression is less than zero.
Solve 2x² plus 12x equals -10 by completing the square?
I assume you mean the equation 2x2 + 12x - 10 = 0. Divide by 2: x2 + 6x - 5 = 0 To complete the square, the constant part (the part with no variable) must be half the linear part (1/2 of 6), squared, so in this case you add 14 to each side: x2 + 6x +9 = 14 This can be factored: (x+3)2 = 14 Now, just take the square root of each side: x + 3 = (plus-or-minus) 14 Solve the resulting two equations (one for plus, one for minus).
X2 plus 20x equals 30 solve by completing the square?
x2 + 20x +0 =30 [(20/2)2 =100] x2 + 20x + 100 =30 +100 √(x+10)2=√130 x+10=√130 x= −10+√130 √ means square root
What does the equation y equals x2 - 6x plus 2 become after completing the square?
y = x2 - 6x + 2 y = x2 - 6x + 9 - 7 y = (x - 3)2 - 7
What are the solutions in completing the square x2 plus 6x equals 7?
x2 + 6x = 7 ⇒ x2 + 6x + 9 = 7 + 9 ⇒ (x + 3)2 = 16 ⇒ x + 3 = ±4 ⇒ x = -7 or 1
How do you solve x2 6x 27?
please help on this x2+6x+27=
If x is a positive integer solve x2 6x 16?
Um.......is it x2+6x or x2-6x. I think your missing some things here champ
Solve by Completing The Square y equals x2 plus 6x-7?
x2+6x-7 = 0 (x+3)2-7 = 0 (x+3)2-7-9 = 0 (x+3)2 = 16 x+3 = + or - 4 x = - 3 + or - 4 x = 1 or -7

How do you solve x2 - 6x - 13 equals 14?
If: x2-6x-13 = 14 Then: x2-6x-27 = 0 And: (x+3)(x-9) = 0 So: x = -3 or x = 9
Is there a math problem that cannot be solved by completing the square?
If you aren't dealing with algebra, such as x2+3x+21, then completing the square wont be able to solve the porblem, however if you are using algebra, and you cannot factorise, then completing the square will always work
How do you complete the square x2 - 6x equals 16?
x2 - 6x = 16 ∴ x2 - 6x + 9 = 25 ∴ (x - 3)2 = 25 ∴ x - 3 = 25 ∴ x = 28
How do you solve x2 plus 6x equals -9?
2x+6x=-9 => 8x=-9=> x=-8/9
Can you solve by completing the square x2 plus 10x plus 220?
No because the discriminant of the given quadratic expression is less than zero.
