This video tutorial from Mumu Math and Science explains how to factor a trinomial where the leading coefficient is not 1. The process involves using the X method to find two numbers that multiply to the product of the leading coefficient and the constant term, and add to the middle coefficient. The middle term is then split, and the trinomial is rewritten. The greatest common factor is factored out by grouping, and the final factors are written out. The video emphasizes the importance of matching terms in parentheses and concludes with a reminder to be kind.
