Math blog post Week 10// Self assessment – Critical thinking

This week, i went over 3 things that i forgot how to do. The first one i did was rationalizing radicals. I knew the general idea of this, but i forgot how you have to multiply the conjugate making it a zero pair rather than multiplying by the same thing. For my second one, i did arithmetic sequences, i didn’t forget how to do it, it was just a memory refresher. And for the last one, i did solving discriminant which tells me how many roots i have and this was confusing for me on the test, because i would divide it by 2a.
