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 complete the square for the expression (x^2 + 9x), take half of the coefficient of (x) (which is 9), square it, and add that value. Half of 9 is (4.5), and squaring it gives (20.25). Therefore, the number that must be added is (20.25). Thus, the completed square form is ((x + 4.5)^2).
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.
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) }.
