Jorge's Class
Daily Updated Notes
Started off...Started off with receiving our tests back. If you did not like your grade, you could retake the test this Friday. The retake will not be multiple choice, but the white boards with notes will be erased and what you get on the retake will be your final grade. Please ask someone for help or tutor you, and come in for lunch of after wards so that Jorge can answer your questions! NotesNo notes for today!

Started Off...Started off class with saying that our test will be graded during class and you'll find out your score. Meanwhile, completing the four study guides if you didn't finish them and turning them in for credit. When done, there were problems on the board that introduce the next concept that we'll be diving into. NotesForgot to take a picture of the board, sorry.
Started Off...Started off in class with starting on the practice test that was handed out. Which is practically how the the test will be tomorrow. NotesTomorrow is the test and don't forget to bring a calculator, your note card and good night's rest!
Started Off...Started off in class with knowing that are midterm is in one week and that we will have 4 study guides this week to prepare for the test, each of them worth 5 extra points. Also a practice test on Friday which is not graded, only 15 extra points if you try to do it. NotesThe first study guide was passed out today, it's posted on the worksheet page!
Started Off...To get ready for the test, we were given three equations and having to use the methods that we've learned so far to solve them. Graphing them, finding x & y intercepts, minimum/maximum, and vertex. These type of problems will be on the test and so by doing this we get extra practice. NotesNo notes for today! Remember that if you go to dance tonight you ear 15 extra credit points for attending!
Started Off...Continued with the quadratic equation page and if you were finished you could work on honors for math. NotesNo notes, just that the quadratic formula page is due at the end of class Friday!
Started Off...We worked on the worksheet that was passed out yesterday during the whole period, asking questions when we needed and asked each other for help. NotesNothing new was taught until #15 and over, there were more steps to complete with the equations given to you.
Started Of...Started off in class with reviewing the worksheet that was given out yesterday. Answered questions that students had and moved on to a new concept. Learning how to go from standard from to vertex form and how to factor it out and find the x intercepts. There was also another worksheet passed out, that is not due as far as we know. NotesSame concept as yesterdays, but with negatives.
Also, and equation (b/2)^2 is helpful. x^2 + 2x - 3 = 0. First add on both side to get x isolated. But. when you do that, another number will replace where 3 was. You'll replace it with 1. Now you have a oerfect square, meaning you can put it into standard form. x^2 + 2x + 1 = 4 ---> (x+1)^2 = 4. Now square root both sides to get rid of the squared, and you will have a negative & a positive 2 = x+1. Subtract 1 on both side. 2-1 = 1 & -2 - 1 =-3. -3 and 1 are your x intercepts. Started Off...Started off in class with a warm up, eventually leading up to the lesson that we learned about today. The lesson was on finding x intercepts/roots/zeros/solutions, how standard from equals to vertex form and equaling them to zero. Also, there was a worksheet that was passed out and was only classwork. Notes Standard Form - x^2 + 8x + 15 Vertex Form - (x+4)^2 - 1 Are these the same? Are the equal to each other? If so how? Why? We answered tehse questions. Starting with standard form, you can factor that out easily. (x+3)(x+5) and equal them to zero. Giving you x = -3 & x = -5. Lets see what we get with the vertex from. First you want to get rid of the -1 that is there because it'll get in the way of the next step. So you add +1 on both side. Now you square root both side to get rid of the squared. All you have now is 1=x + 4. BUT the 1 is now a negative AND a positive (because a + & + is a + and - & - is also a +) which is crucial. Subtract 4 on both sides meaning 1 - 4 = -3 & -1 - 4 = -5. -5 & -3 are your x intercepts which is what we got with the standard form. |
