    This is a great lesson to watch to learn how to factor trinomials with a leading coefficient. These trinomials can be difficult to factor because there can be so many possibilities, but this lesson does a great job of explaining a method for finding factors by eliminating certain numbers and testing the factors out without actually multiplying the binomials.
