Help with Lesson 7.6 homework from lesson 7.5/7.6 Day One

Show Transcript

Okay, claire. I'm going to help you out with the homework tonight lesson 7.5 and 7.6 Day 1. Specifically, I'm just going to help you out with that lesson 7.63 through 7 odd and I put them up in 3 different videos, so this first video is number 3. if you want to proceed to get help on number 5 in 7 you would have to click and open up the video number two and then again of the Patrice I did I'm in sequential order, okay. Hope to get started with this polly email, and I wrote down for you 3x squared + 3x - 6 are. Step would be to do an x factor after the side we would multiply arleen coefficient 3 x -6 we get -18 we would put our. Calm down below which is a positive 3 and you're welcome to put the positive there now. We have to come up with factors of -18 that would also add up to 3. You should come up with a 6 and 3 but noticed that we still have to get a -18 and a positive 322 combine. in 318 I would need to have a -3 and a positive 6 to add up and get positive 3 and that again would multiply to get a -18 to kind of Will check your terms and then you bring them over here and do your split good method. So we're going to split this polynomial as a two parts. I'm going to put the -3x next to the 3. In the positive 6 x next to the 6th and again we can.  Put these terms as we're adding them and both multiply. different order because of the community property okay, so we're going to group now after we split this middle term afraid and we're going to The greatest common belfast common model Factor, Adam. H final bill starting with the first battle I would pull out the 3x. and I do left with x minus 1  I'm going to pull out a 6  and I'll be left with x - 4 again. This is good because I one of my factors is x -1 and the other factor is 3x + 6  hi be very happy with this answer. Can you can fax it and highlight it and be done and move on to the next video, but I want to show you something some highlights as in yellow cuz again. This is very acceptable that's You might notice that in the back of the book of this is on this is not the answer they have so what are things were going to build on from this lesson is talking about factoring completely. And what you should notice it when you look at this 3x + 6.  Week, they share yet another common mana meal factor. So we could actually factor out a 3 from the 3x + 6 to leave you left with x plus 2 which. I believe is the answer in the back of the book. We'll talk more about that tomorrow. So you are also welcome to copy this answer well.  This 2/8 to do it. There's the way of Factory at the End when you noticed that way I could keep factoring this and the other way which we're going to talk about tomorrow is going back up to you're trying to mail, and maybe noticing something you. About each term in this training meal before I do my secret method notice I have a 3x squared + 3. X -6 We can in fact factor out the greatest common model Factor, but Rhino mill before doing the slip? Nothing, just like we did when we factor or by no mills. It's not something that students off and look for so I'm going to teach you a number 5 and number 7. You'll notice it in the x factor when your numbers are really large, and you think this is a big number. Which -18 is not you might go back and look to see if there's a Tom and monitor you can factor up first, so if you accepted the 3 out first you would have said only factor of 3 and had a different try no mills. Squared + 1x - 2 cuz I was factor 30 this entire trying a meal and instead of this x factor I would. this x Factor and came up with terms like 2 and -1  but Seen about two and -1 is they add up to get positive 1 multiplied to get -2 and they also happened to be?  related The two Factors that are left in the answer when you factor this completely we will talk more about this tomorrow and Monday, but for now I look. Any one of these answers and good luck again if you want to see number 5 and number 7 click on the other two videos.
