This week we have learned/finished studying the quadratic functions for the test we had on Wednesday.  The word “quadratic” sounded so big and scary at first because I had no clue what they were.  I sometimes doubted myself in memorizing the formulas before I started practicing and watching videos online about how to solve each question.

0.5x^(2)-0.4x-1.2 was a question on the test practice which I found very hard at first then figured out the answer which was (5x+6)(x−2).
