Factoring Quadratic Expressions

The video tutorial explains the product sum factoring method for quadratic trinomials. It begins with an introduction to the method, followed by three examples: factoring x^2 + 2x + 1, x^2 + 7x + 12, and x^2 - 5x - 36. Each example demonstrates how to identify factors that multiply to the constant term and add to the linear coefficient, including handling negative signs.
