UNIT 3 - Quadratic Functions
Quadratic Formula / Discriminant Example:
Factoring Practice...3 videos below:
Hi Class, we are going to do todays lesson with videos since I'm out today. Before you get started, please
- get out your Unit 3 Homework and Notes (the guest teacher will give them to you).
- get out something to write with.
STEP 2: But wait, now that you get the concept, there's a quicker way to do this. now let's do Problem #2...but in an easier way!!!!
STEP 3: You are doing very well. Before moving on, finish problems 3,4,6,8 and 9 from your 3.1 homework.
STEP 4: Now we are going to solve a quadratic where there IS A NUMBER IN FRONT OF THE X SQUARED. To do this, we are going to go to our note packet. Please open your notes to page 2, let's do Example 1 together with the video below:
STEP 5: You can use the same method to solve problems #10 and #12 from the 3.1 homework. Give those a try.
Conclusion: When you come to class on Tuesday, I'd like you to have problems 1,2,3,4,6,8,9,10, and 12 finished from the 3.1 homework. You now know how to find solutions to a quadratic without using your graphing calculator, great job!
THIS ENDS YOUR LESSON FOR MONDAY, GREAT JOB!
