'h' and 'k' are just place holders. They, like 'a', can be anything.

@loser66 why did you add 4 and subtract 4?

As @Loser66 pointed out, by adding (+4) and subtracting (4) you are adding 0 to the equation.

Is this completing the square?

Similar in principle but not the exact same thing. You are just massaging the equation to fit the form you need, without changing anything.

It's like multiplying two fractions to get a common denominator, or changing both sides of an equation equally, they are all about getting the numbers to "look" like what you need.
