Factoring Trinomials with Diamond and XBox Methods

This video tutorial demonstrates how to factor a trinomial where the 'a' value is not one, using the diamond and Xbox methods. The instructor explains the setup of the diamond method, finding the product of 'A' and 'C' values, and identifying the 'B' value. The video then guides viewers through finding two factors with a specific product and sum, and using these factors in the Xbox method. The tutorial concludes by completing the factoring process and writing the trinomial in its factored form.
