Answer:
16 is added to each side of the equation.
Step-by-step explanation:
Once the coefficient of [tex]x^{2}[/tex] is 1, then divide the coefficient of the x term by 2 and square the result.
In your case the coefficient of [tex]x^{2}[/tex] is already 1, so divide the coefficient of x which is 8 by 2 and square. 8/2 = 4 4 squared = 16
Therefore, 16 is added to each side of the equation.
Note: You cannot complete the square until the coefficient of the [tex]x^{2}[/tex] term is 1. If it isn't 1 then divide thru the equation by the coefficient [tex]x^{2}[/tex].
Hope this has helped. Completing the square is NOT a fun exercise, but it is necessary to know how to do it.
