This week was mix, with mostly grade 9 review and some new concepts about polynomials. I had some struggles at the beginning but now I am pretty confident with my work. What has made me really be more successful was making mistakes, I then would learn exactly what I did wrong and never let it happen again. There was one question that we did that really stood out to me as a learning point. This question I got wrong the first time but eventually figured out what i did wrong, now I know how to do every question that is similar to it. Here is a video I made of an example of my mistake and my correction.
Another thing I learned that i thought was really cool was about the patterns we can use to solve/simplifly the simple binomials. A simple binomial is one that starts with an x and then a constant it would not include any exponents. Here is an example one and (x+6)(x-2)
The pattern is to multiply the x’s, add the constant terms and add an x at the end, and then multiply the constant terms. This is a faster way for me to do the simple questions all in my head. I think that it is really cool how we can use patterns in lot of different things, like in polynomials and math. Here isan example for you to better understand the pattern we use.
