You need to understand the standard form of a polynomial first. Once the polynomial is in standard form, it's obvious. So for example 3x^4 + 4x^2 + 7x -1 is missing the x ^3 term. Look at your exponents, they go in descending order. In my example, we started with the 4th power, missed the 3rd power, then saw a 2nd power, and 1st power.
@Zzz Z You have the number 1 on the right-hand side and want to write it as the difference of two polynomials? The answer wouldn't be unique here because you don't have enough information. For example. 0x + 5 - (0x^2 - 0x + 4) = 0x^2 + 0x + 1 Also 0x^2 + 0x + 7 - (0x^2 + 0x + 6) = 0x + 1 Is there an actual example that you are working on?
Hello. “When terms are missing…” How do I identify that a term is missing? Thank you for your help. (I realize this video is very old, but perhaps you’re still connected. 😊
You go in descending order. In other words, if you have x^4, then you need x^3, x^2, and x. If you are missing one of those, then you need a 0 as a coefficient to act as a placeholder.
The equation? This is for dividing polynomials only, you shouldn't have an equation. It should look as it does in the video. If this is the case, you will write a zero in as a placeholder for the missing term when you set up your long division and proceed as your normally do. Hope this helps :)
@@einaflores900 No it's cool, a lot of people watch the wrong video, so I have to guard against that. If you are dividing with polynomials and there is a missing term, just write zero as the coefficient and proceed normally. For example if you had 3x^2 - 5 / x - 1 then in the numerator you are missing the x^1 term. You can re write this as 3x^2 + 0x - 5 / x - 1. Let me know if you have an example that you are stuck on, I am happy to try and help :)
I always get confused on when to subtract and when to add when you have positive minus positive, negative minus negative or positive minus negative. I saw another video where it was a positive minus a negative and they added. On your video you have positive 20 -- (minus) -20 (negative) and you subtracted. The other video was 4x^2 -- -3x^2 and it was added to 7x^2. I'm confused??
You need to review Pre-Algebra and the rules of integers before taking Algebra. If you leave a time marker, I can look at that part of the video and explain what's going on.
Look for your highest power on the variable, then make sure you have all the powers in descending order. In other words if you have an x^3, then you want an x^2, and x^1.
You're fabulous and I love you. I feel like showing my teacher this and saying "This. This is how you do the teach." xD
I'm so glad the video was helpful! :)
This is the greatest video on the internet. Thank you so much.
You are very welcome! :)
Thank you very much good sir!!
Very welcome!

For example.
0x + 5 - (0x^2 - 0x + 4) = 0x^2 + 0x + 1
Also
0x^2 + 0x + 7 - (0x^2 + 0x + 6) = 0x + 1

@@SheriCarthan-MinistryHelp You are welcome.
thank you this genuinely helped so much !!
I'm so glad!
Thank you for this!🥰
You are very welcome! :)
Thank you! This was really helpful :)
You are welcome! Let us know if you get stuck on a problem! :)
What if the equation is negative should I also change the sign of the missing term to negative?

Oh i mean the polynomial sorry my mistake :)

Thank you for sharing. Helped me out with my technical math class.
You are very welcome! :)
How do you know if your missing a term though that’s where I’m stuck at help please!!

@@Greenemath Thank you so much
@@joshuaanderson9938 You are very welcome! :)
What if you have a missing term in your divisor?
Same idea, use 0 as the coefficient for the term you are missing. If you go through to the next video it will have an example.
You're welcome :0
