To balance a equation, the whole number added or used in front of a compound is known as Coefficient.
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
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) }.
It is called a sum or an equation
