Thank you very much. Happy to help.

That’s probably because there is different ways to do it

@@joshwhite5730 Agreed! Most concepts have many different routes to a solution.

​@@thebielecmethod4884what do I do if the second difference is not the same?

Love to hear it. Feel free to request videos anytime!

We half the 2nd difference an^2+bn+c first four terms in a sequence of 1,2,3,4 produce a 2nd difference of 2a. By dividing by 2 we have now isolated the value of “a”. I will make a video explaining this and showing it as a proof.

Are you sure your dealing with a quadratic?

Anytime! Thanks for the support

Happy to help. Feel free to request videos in the future.

Great question! Always take the second difference you find and cut it in half. For example: if your 2nd difference is 4 then your "a" would end up being 4/2, which is just 2. Let me know if this helps.

@@thebielecmethod4884 Thank you!!

Anytime!

Absolutely! I’m away on vacation, but can post it on Monday for you. Hope that works.

Love to hear that I can have an impact all the way over there. Thank you for the support!

Anytime! Thank you for the support.

Did you mean a y-intercept? Here is another video where you do not have a zero for x. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-g6Ns3ISjSKU.html There are many other ways, and I can make more videos if needed.

No doubt! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-7BAhywu9BpA.htmlsi=mGWZVWns0hsK6Suj Here is a link to an old video that introduces vocabulary of quadratics and I will do my best to get a video uploaded for you this week about graphing them. This video will help you understand what parts you’ll want to find first.

It sure does! Second difference in this case is -2

This would mean you are not dealing with a quadratic. What is your second difference giving you?

Thank you for the support!

Yes the same rule applies as long as the x values increase is constant.

In this scenario you need to set up 3 equations with variables typically being a, b, c. You then solve a system of 3 equations using elimination or substitution method. I can fill a video of this if you’d like me to post one this week for you.

​@@thebielecmethod4884yeah pleade

Once you have the equation written out, you replace the x’s with whatever given value you have, then simplify the quadratic down to y= (whatever number you end with) Example: find corresponding y value for x=3 in y=2x^2+4x+3 You now have y=2(3)^2+4(3)+3 18+12+3 Y=33 If this doesn’t help I can make a video showing an example for you. Thanks for the support.

New Zealand! I love it! Very happy to help. You live in the most beautiful land in the world in my opinion.

@@thebielecmethod4884 cheers, just had the exam, and this video certainly came in handy.

@@mamingakuri2436 So happy to hear that! feel free to request videos anytime. I try my best to upload when I can find the time to help out. Congrats on completing the exam!

The a term can be both positive and negative.

Anytime!

Thank you. Hope the videos are helping!

Sometimes you can work backward towards zero.

Happy to help! Request videos anytime!

Absolutely! Thanks for the support. Happy to help. I won’t be back at the school until Monday however so I hope that’s ok. I’ll send you a link when I upload it.

@@thebielecmethod4884 Thank you so much!!

@hdhdhd-pv6yo anytime!

ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6fzVL8LpsPg.htmlsi=F8yHRydJT4ObAtqP This should help you through Prime Factoring. Let me know if you need anything else.

That means it isn’t a quadratic function.

Usually the best way to go about this would be to create 3 separate equations with replacing the x and y’s in each of the 3 with the values provided. For example (2,8) when replaced with y=ax^2+bx+c, would be 8=a(2)^2+b(2)+c. This would then simplify to 8=4a+2b+c. Once you have the 3 different equations you will solve the system of 3 equations with 3 variables. This will give you the a,b and c values for the quadratic. I’d make a video but I’m on vacation until Saturday. If you still want a video, let me know and I’ll film it when I get back home. Thanks for the question and I hope this helps.

@@thebielecmethod4884 ya sure, I would love the video. I tried looking all over youtube for a video that explained what to do if the x values did not go up by 1 and I couldnt find any. Have a blessed day and thank you for actually replying to my comment :)

Happy to help. I’ll shoot you the link once I get back and post it.

@@thebielecmethod4884 ok thanks

Anytime!

Your second difference is constant so just work the x value back following that pattern until you get to x=0. I can make a video next week for you and send a link.

In what choices?

@@thebielecmethod4884 on the activity that my teacher gave us. But i got the answer now.

Anytime!

I will make a video for you on this sometime this week. You will need at least 3 points, none of which need to have x =0

@@thebielecmethod4884 did you ever make that video? I also need to find C when I dont have the value of X=0

zero still on a step , I have case that zero is amoung numbers and not a regular step, also I had applied this method and a didn't come right @@thebielecmethod4884

It is also taught in Algebra 1, but we go more in depth when in Algebra 2.

Send me the x and y values your dealing with and I’ll make a video with another method of getting it

Oh man I hate hearing that. Hopefully my channel can get you back on track. Please request any videos you need for support.

Anytime!

Thanks for the support!

Great question! The c value would be zero. So in the equation you would only have 2 terms on the right side of equal sign instead of 3. The ax^2+bx

Oh snap!

I do not.

Thank you very much!
