Once in a while, though, trinomials go through mood swings and stop cooperating, and then we have a bit more begging and pleading to do. What do we do in those instances? One method is to try trial and error.Sounds like something your teacher would advise trial and error you not to do, but if you've got a talent for seeing patterns, you like guessing games, you’ve done all your homework and have a lot of time on your hands, or you’re just not a rule follower, this is the method for you. If none of this trial-and-erroring can get a quadratic polynomial out of its bad mood, about all there is left to do is take it for ice cream and then put it down for a nap. Hopefully it won't be quite so pouty when it wakes up.Remember that a quadratic polynomial is a polynomial of degree 2 of the form ax2 + bx + c.These polynomials are easiest to factor when a = 1 (that is, the polynomial looks like x2 + bx + c), so we'll look at that case first. Those of you who like torturing yourselves can skip ahead to the harder stuff.Before we start factoring, we'll revisit multiplication. Assume m and n are integers. You're not being presumptuous—they are integers, we swear. If we multiply:(x + m)(x + n)...then we find:x2 + mx + nx + mn...whic
factor trinomials with a leading coefficient that is greater than 1, such as 6x^2 - 25x + 24. There are two 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 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 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. Some students don't like it because there is no definite procedure leading to a solid "answer". Some students do not like trying, and trying, and trying, until they find the right factors. Grouping Using grouping makes use of the students' knowledge of FOIL. To factor 6x^2 - 25x + 24 using grouping, we need to
