It's the locus of a moving point that keeps the same distance between a stationary point and a specified line. The focus is a non-movable point, while the directrix is a non-movable line.
Let the quadratic function be y = ax² + bx + c.
The first step is to take common the coefficient of x². We have

Add and subtract the half of the square the coefficient of x,

Then we have

These are the required step to get the perfect square of the quadratic function.
