Factor a trinomial by first factoring out the GCF

The video tutorial explains how to factor a trinomial by first identifying the greatest common factor (GCF) and then factoring the trinomial into two binomials. The process involves checking for common factors, writing down factor pairs of the constant term, and ensuring the middle term is achieved by adding the inner and outer products. The tutorial concludes with the complete factorization of the trinomial.
