In completing the square method, considering the equation X^2 - 2x + the number to be added should be<u> 1 </u>to make it a perfect square
<h3>How to know term that should added</h3>
The standard quadratic equation is of the form
ax^2 + bx + c
The completing the square method is one of the methods of solving quadratic equations
The factor to be added to the equation while using the completing the square method is of the formula
(b / 2a)^2
compared to the equation in the problem X^2 - 2x +
= (b / 2a)^2
= (2 / 2)^2
= (1)^2
= 1

Answer: -1
Step-by-step explanation: To evaluate this problem, the first thing we want to do is plug in the appropriate value for <em>x</em>.
When we do that, we get 
A good rule of thumb for problems that involve division bars is to simplify what's above the division bar as much as you can and what's below the division bar as much as you can before you do your dividing.
So up top if we follow our order of operations, the first thing we want to do is square the -2 before we subtract. So -2² is +4.
So in our numerator we have 4 - 8.
Down below, we have -2 + 6 which is +4.
4 - 8 is -4 and -2 + 6 is +4.
