Resources to Benefit EVERYONE

We will be spending the majority of next week (March 24-29), on our last and most difficult factoring method; factoring trinomials with a leading coefficient greater than 1. The video below covers this factoring method step-by-step. I think everyone could benefit by watching and practicing before we introduce this concept in class (Wednesday).

Additionally, one of the Khan Academy topics this week, Factoring Quadratics 2, requires factoring by this method.  The name for this method of factoring is, "Factoring Trinomials by Grouping", since you will take a three term polynomial, add a term, and then factor the four terms by grouping. 1. 2(x-4)(3x+1)    2.  3(x + 5)(x - 2)

Here are two practice problems to get you ready. Always look for a GCF first.
                            1. 6x^2 - 22x - 8                               2.  3x^2 + 9x - 30

The solutions are both on this post. Find them after you have completed the problem.
