Factoring trinomials

The video tutorial explains how to factor a trinomial by first identifying the greatest common factor (GCF) and then using the box method to factor the expression. The instructor demonstrates how to find two numbers that multiply to the product of the first and last coefficients and add to the middle coefficient. The tutorial also covers recognizing perfect squares and using grouping to simplify the factoring process, ultimately leading to the final factored form.
