For a quick way to find the vertex of a quadratic, use the formula x = -b/2a and then y = f(x). Done and done.
Easy peasy! Use the formula h = -b/2a and then plug h back into the equation to find k. Voila, you have your vertex (h, k)!
Just do -b over 2a for the x-value of the vertex, then sub this x back in the equation to find y. Simple as that!
