To complete the square for the expression (x^2 + 12x - 6), we need to focus on the (x^2 + 12x) part. We take half of the coefficient of (x) (which is 12), square it, and add it to both sides. Half of 12 is 6, and squaring it gives us 36. Therefore, we must add 36 to both sides of the equation.

To balance a equation, the whole number added or used in front of a compound is known as Coefficient.
They fit the equation t = 0 exactly.
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
Without an equality sign it can not be considered to be an equation

Adding 100 completes the square. { I wonder why you want to complete the square when the expression already factors as x(x-20) }.
It is called a sum or an equation
