Let f (x) be a quadratic equation of the form:

Where b and c are real numbers.
So a generic procedure for completing squares is:
1) identify b
In this case b = 10
2) divide b between 2 and then square it


3) Add and subtract
in the equation


4) Rewrite the equation as follows


The number that you must add to both sides of the equation is number
