Factoring a trinomial a = 1

The video tutorial covers the process of factoring a quadratic expression, specifically t squared plus 8t plus 12. The teacher explains the concept of factoring, the importance of identifying the greatest common factor (GCF), and the steps involved in factoring the expression. The X method is introduced as a tool to find factors that multiply to the constant term and add to the middle term. The tutorial concludes with a verification of the solution using the FOIL method to ensure the expression is correctly factored.
