Turning any quadratic into a perfect square plus a constant, the one rule that makes it work, and why the vertex falls out of the result for free.
Use the quadratic formula for ax²+bx+c=0, identify coefficients correctly, simplify the discriminant and interpret resulting roots.
Solve quadratic equations by arranging them equal to zero, factoring completely and applying the zero-product property.
