The video tutorial covers the topic of fractions and quadratic equations. It begins with an introduction to fractions and the vertex form of a quadratic equation, explaining the concept of the vertex as HK and the opposite of H. The tutorial then moves on to finding the vertex in a quadratic equation, providing a step-by-step explanation. Finally, it demonstrates how to solve the quadratic equation using inverse operations and the square root method to find the solutions where the graph crosses the X intercept.
