Big fan of this. It does skip the actual derivation, but maybe that’s the sane thing to do for a wide audience?
I would still introduce the formula before completing the square, then finally showing how they relate (probably days, maybe weeks later.)
What do you think?

Hi Adam, I take your point that the quadratic formula can be presented in a way that does not inspire understanding or affection. And it sounds like that's how it was taught to you. So let me try to make a better case for it. Here's how I discussed it in my book The Joy of x. (1/9)
