Factor a trinomial using ac method when you have a coefficient for quadratic term

The video tutorial explains how to factor a trinomial using the AC method. It begins by introducing the concept of factoring and the importance of identifying the coefficients in a quadratic expression. The AC method involves multiplying the coefficients A and C, then finding two numbers that multiply to this product and add to B. The tutorial demonstrates how to replace the middle term with these factors and use grouping to factor the expression completely.
