Best ResponseYou've already chosen the best response.0'h' and 'k' are just place holders. They, like 'a', can be anything.

Best ResponseYou've already chosen the best response.0As @Loser66 pointed out, by adding (+4) and subtracting (4) you are adding 0 to the equation.

Best ResponseYou've already chosen the best response.0Similar in principle but not the exact same thing. You are just massaging the equation to fit the form you need, without changing anything.

Best ResponseYou've already chosen the best response.0It'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.
