Week 10 in Precalc 11

This week because the midterm is coming up, we spent the week reviewing in preparation. I mostly went over reviewing ideas from chapter 1. Finding the difference is something critical because “d” is a variable used in almost every formula used for sequences and series, this is the same for the second idea I reviewed where instead I have to find “n”. With the third idea, using the quadratic formula, is another way of factoring. This is important because factoring was not only needed in chapter 3, but a concept needed for the future chapters. knowing how to use the quadratic formula is also critical since knowing this formula can also be used to find the discriminate.
