Vin, when you do completing the square ALWAYS mention that when you factor the LHS to be a perfect square trinomial, it’s always x followed by half the linear term, quantity squared. I would not know this if it wasn’t for another YouTube channel that saved me on the regents exam. Try to teach as many shortcuts as you can. It saves lives!!
