The video tutorial covers quadratic forms, focusing on standard form, vertex form, and intercept form. It explains how to extract information such as zeros, y-intercepts, and vertex coordinates from standard form. The tutorial also discusses parabola orientation and the importance of memorizing key formulas. Example problems are solved to demonstrate these concepts, and the process of converting between different quadratic forms is briefly touched upon.
