Factoring Trinomials with the Box Method

The video tutorial explains how to factor a polynomial by multiplying the leading coefficient with the constant term and finding two numbers that multiply to this product and add to the middle coefficient. It introduces the box method to organize terms and calculate areas representing polynomial terms. The tutorial concludes with the final steps to factor the polynomial completely.
