This week was all about factoring and QUADRATICS!!! I just did a super long video (sorry) on what we have gone over thus far! Enjoy!!
This week in Precalculus we started a new unit! Solving Quadratic Equations. We primarily focused on review and factoring Binomials and Trinomials. I enjoyed this last year, so I liked this week. Of course it was not the same as last year, but I learned and revisited the idea / synonym; CDPEU… and that is what I am going to be talking about in this Blog Post! I will provide a silly sentence to remember this trick and an expression to go with each letter! So far, this helpful hint has been used in almost everything we have done. Enjoy 🙂
This week was short. Monday we had our test for Sequences and Series, Tuesday we had a snow day, Wednesday we started review on Roots and Radicals with a new element of Absolute Value and today we continued with those ideas and completed the Checkpoint questions. This week was pretty low-key. What I will be highlighting in my ShowMe, was what I struggled with most – When there is a fraction under a root sign. I enjoy attaching ShowMe’s as it allows my viewers to see the specific steps, along with hearing my voice; It has most learning styles included! Hopefully it works for you. As I said, you will be watching how to solve for a fraction being placed under a root sign, some mixed and entire radicals, along with a question or two of solving for an Absolute Value.
This week wrapped up our first unit! It was generally based around Geometric Sequences and Series. For myself, it was a step higher from Arithmetic Sequences and Series and slightly more challenging. Due to formulas, solving the questions in the workbook came with ease… except word problems. Therefore, I thought I would demo one for my Blogpost this week!
Week 9 Math 10….
This week we finished up polynomial expressions and began Factoring polynomials. There are different ways to find the answer to a polynomial expression.
If your expression was:
Then one of the many ways you can solve the answer is using an area model. This is a faster way to find a answer then using tiling models.Here how you would set it up:
In black I have show the expression.
In orange is the area model diagram.
In pink is your answers for going left and top. Each time.
Therefore your answer is in the pink.
I told the story well however, I need to improve on punctuation in sentences.
The point of view I chose was objective.
Knocking at the door he ran down the stairs, collected himself and opened the door. With a deep breath he invited the three police officer’s in to talk. He place three chairs in the exact room the fresh cut up body rested under the wooden planks. He acted cool with all of this. Slowly a sound grew louder in his head. It was the heartbeat, the heartbeat he claimed to be the old mans. Louder and louder he began to go insane. He began cursing, he raved and he foamed. He through the chair to the side ripped the wood planks up, yelled: “HERE, HERE!” The body was shown to the police officer’s and they knew, the knew the truth; this man was criminally insane. The three officer’s soon clenched cold, metallic and heavy handcuffs to the crazy man’s wrists. He would be locked up for the rest of is life.
