I don’t know about you, but I’m starting to see the light at the end of the tunnel! Now that today is over, you only have 5 days left in this class, and two of those days are for finals. This means that there is not any time to spare, this is it. Sink or swim.
Today we looked again at quadratic equations and solving them three different ways. These three ways include graphing, factoring, and the quadratic formula. Those are the three biggest methods that you NEED to know. They won’t go away, so the sooner you learn them, the better you will be. Tomorrow is yet another review day…stay tuned!

Assignment – More Solving Quadratic Equations
That’s all we have remaining of the Fall 2018 semester. This could make or break a few of you, so it’s time to kick it into high gear and get your act together! Don’t delay!
For the review today, we looked at linear functions. This involved things like graphing them, writing the equations of lines, finding the slope, finding x- and y-intercepts, and so much more. See the notes for all the details and have a FANTASTIC weekend!

It’s official – we have started our review for the final exam. Yep, you read that right – FINAL EXAM. So from now until the end, there won’t be anything new…unless you didn’t learn it to begin with 🙂
For the first review, we looked at solving linear equations. This ranged from solving actual equations for an unknown to writing algebraic expressions when given words (verbal expressions). It was a quick lesson, but hopefully it helped to knock off any cobwebs that may have developed since August.

Does that not feel good to say?! Today we saw the last unit review of the semester. After we take the test that’s looming tomorrow, we will start reviewing for the final and then take the TSI Test. Even though it feels like the pace is picking up, we are really just slowing down because there won’t be any new material for the rest of the year. So, study up for this last unit test and make it count!
Review – (A53)Review Quadratics
Review Notes – L9-8 Notes for Review
I bet a lot will be relieved to know that we have pushed the Solving Quadratics unit exam back to Wednesday, Dec. 5th! This gives you another couple of days to make sure you know the material in order to do well on the test.
In other news, we looked yet again at how to choose the best method for solving quadratic equations. What works for one equation may not work for another, so we have to go on a case by case basis. The list below summarizes the pros and cons of each:
- The square root property will only work if there’s no “x” term.
- Not all quadratics are capable of being factored.
- For graphing to work, the roots need to be pretty.
- The quadratic formula always works but is very tedious.
Have a wonderful weekend and good luck on the English 1 STAAR test if you are taking it Monday!
Notes – L9-7 Solving Quadratics using Any Method
Assignment – (A9-7) quadratic equations any method
… Just don’t pick your friend’s nose.
Speaking of picking, that’s what we were doing today – picking the best method to solve a quadratic equation. We’ve covered four methods in this unit that are useful in solving these equations:
- Square Root Property
- Quadratic Formula
As we briefly mentioned today, each method has it’s pros and cons. Some work when others won’t, but the Quadratic Formula never fails because it’s the Manly-Man of methods! However, it is very tedious and time-consuming! We will talk more in detail about putting the different methods together during the lesson tomorrow…Stay Tuned!
Notes – L9-6 Choosing a Method for Solving Quadratics
We had a little blast from the past today for the lesson and notes! Okay, maybe it wasn’t that far in the past, but it was still something that we saw back in the last unit. What was it, you ask? We found the zeroes of quadratic functions using graphs and tables! A lot would say it was easy-peasy, lemon-squeezy and that’s a good thing because it means you are becoming professionals at finding those sneaky little things! Nonetheless, it was nice to have a easier day today. Catch ya on the flip side of this night!

This will be quick, as I’ll have two posts today. However, the website has been down for the past few days. Nonetheless, here are the Notes and Assignments from Monday and Tuesday:

Assignment- (A9-3) Quadratic by factoring D2
Notes – L9-4 Solving Quadratics using the Quadratic Formula
Assignment – (A9-4) quadratic by formula
Can you taste the turkey, ham, and dressing yet? We have only half of a day left and then we are out for the break. That means today’s assignment was the last normal assignment before the break (and the last time you’ll here from me on here for a while). Tomorrow, we have a math-related “activity”, but there won’t be anything to make up.
However, first things first – today’s lesson. If you remember the factoring unit of last month, well it is here again to grace us with his presence. This time, we will use this method to solve quadratic equations by factoring. This can be down with four easy steps:
- Make sure the equation is equal to 0 and in standard form (ax² + bx + c = 0)
- Factor the equation
- Set each factor equal to 0
- Solve each factor for x.
If you can do these four simple steps, then you have it made! Have a great AND safe Thanksgiving break and I’ll see you on the flip-side!
Notes: L9-2 Solve Quadratics by Factoring – Day 1
Assignment: (A9-2) quadratic by factoring
While we haven’t been necessarily out of school, we have been doing activities, a review, and a test. This means no posting on my part. However, we have a new unit upon us right before the break, so back to posting I go!
While it is a new unit when we are wanting to be in “break mode”, I think you will agree that today was pretty pain-free. Heck, for over 80% of the class, it was so pain-free they had nothing to even take home and had a lot of free time. This is because we were solving quadratic equations using the square root property. This is the easiest way to solve the problem is there is no “x” term in the middle. All you have to do is get x² by itself, take the square root, and then round if needed. See the notes for all the deets…
