factor trinomials with a leading coefficient that is greater than 1, such as 6x^2 - 25x + 24. There are two https://georgewoodbury.wordpress.com/2010/04/21/factoring-trinomials-trial-and-error-or-grouping/ methods for doing this - "trial and error" and "grouping". There are strengths and weaknesses to both approaches. In my experience it is wise to select one method and stick with it, but yesterday I showed both techniques. Trial and Error This method, as its name implies, is all about trying possible factors until you trial and find the right one. 6x^2 can be expressed as x(6x) or 2x(3x), so if the trinomial factors it will be of the form (x-?)(6x-?) or (2x-?)(3x-?). Now we replace the question marks by the factor pairs of 24 (1 & 24, 2 & 12, 3 & 8, 4 & 6) in all possible orders until we find trial and error the correct pair of factors that produce the "middle term" of -25x. The correct factoring is (2x-3)(3x-8). Check for yourself to be sure😉. I like this technique because it helps students develop their mathematical intuition. It is similar to the method we use to factor quadratic trinomials with a leading coefficient of 1. Students can make their work easier by recognizing that the two terms in a binomial factor cannot have a common factor, allowing them to skip certain pairings. For example, (x-1)(6x-24) cannot be correct because 6x and 24 contain a common factor. In the example I gave, there are 16 possible factorizations to check. 14 of the factorizations contain a common factor and can be skipped: (x-1)(6x-24), (x-2)(6x-12), (x-12)(6x-2), (x-3)(6x-8), (x-8)(6x-3), (x-4)(6x-6), (x-6)(6x-4), (2x-1)(3x-24), (2x-24)(3x-1), (2x-2)(3x-12), (2x-12)(3x-2), (2x-8)(3x-3), (2x-4)(3x-6), (2x-6)(3x-4) Only 2 of the factorizations need to be checked: (x-24)(6x-1) and (2x-3)(3x-8) So, a student can really reduce their workload and factor this trinomial fairly quickly.
