In this video, Pak Beni introduces quadratic equations, explaining their general form and how to identify them. The video covers the importance of the coefficient 'a' not being zero and provides examples to distinguish quadratic equations from others. It also demonstrates how to convert equations into the general quadratic form. The session concludes with a preview of the next topic, which will focus on finding roots using factoring.
