We do completing the square as follows:
Write the equation in such a way that the constants are on one side.
<span>x^2 + 2x = 13
We add a number to both sides that will complete the square on the side which contains the variable x.
</span><span>x^2 + 2x + 1 = 13 +1
We factor the side which contains the variable x.
(x+1)^2 = 14
Therefore, we should add 1 in order to complete the square from the given equation.</span>
