This week in math we learned how to solve inequalities, specifically, quadratic inequalities. To solve for these inequalities we require the “zeros” of the quadratic, this means that we must factor the quadratic. With the “zeros” or roots we can… Continue Reading →

This week in math was a review week; specifically, a review and preparation for the upcoming midterm. I was fairly confident in unit 1, but I still had to look over a few of the ideas from the chapter, such… Continue Reading →

What does this artifact tell us about the First World War? From looking at this artifact we can see a lot; although, not literally, we see the cruelty and pain of war. Men spending years of their lives, just to… Continue Reading →

This week in math we learned about how to find the vertex of a quadratic equation that is in factored form. Firstly, you need to find the x-intercepts of the equation. Once that has been found you need to find… Continue Reading →

This week in math we learned about the three different forms to a quadratic equation, all of which are equivalent. The three forms are called, Standard (Vertex) Form, General Form, and Factored Form. Why are there three different forms? Each… Continue Reading →

This week in math we learned about the discriminant. This is part of the quadratic formula, specifically this part,  the letters a, b, and c, represent the coefficients in order of a trinomial from left to right. The reason why… Continue Reading →

This week I learned how to solve quadratic equations using the quadratic formula. The quadratic formula is used to solve quadratic equations. It is most often used when a quadratic equation is non-factorable or hard to factor. With this formula I insert… Continue Reading →

This week I learned how to solve for the difference of squares. To determine if a sequence can be identified as a difference of squares there are three things you should look for. First, you should look if the sequence is a… Continue Reading →

Ralph and Jack are both young tough boys, both strong and yet they both have their own completely opposite leadership styles. Ralph for instance, he cares for everyone and his number one priority is to escape off the island. Jack… Continue Reading →

This week I learned about dividing square roots, this concept was quite difficult at first and it took some time to understand the idea. We learned a topic called “Rationalizing the denominator,” which is removing the root from the denominator… Continue Reading →
