The video tutorial covers identifying coefficients A, B, and C in a quadratic equation, finding the axis of symmetry using the formula X = -B/2A, and determining the vertex by plugging in X and calculating Y. It explains graphing the vertex and choosing points to the left and right, emphasizing the reflection of points over the axis of symmetry. The tutorial also addresses common challenges with fractions and provides strategies for handling them.
