This page demonstrates the process of long division for polynomials using a monic linear divisor, highlighting the steps involved and introducing the concept of synthetic division.
The page shows a detailed example of dividing 2x³ - 4x² + 7x - 11 by x + 2 using traditional long division.
Example: 2x³ - 4x² + 7x - 11 ÷ = 2x² - 8x + 23 + 26/
The process is then simplified by focusing only on the coefficients and changing the divisor to "-2" to facilitate addition instead of subtraction.
Highlight: This simplification process is a step towards synthetic division, which further streamlines the calculation.
This page introduces the concept of synthetic division as a shortcut method for dividing polynomials by monic linear divisors.
The page demonstrates how to perform synthetic division using the same example from the previous page: 2x³ - 4x² + 7x - 11 ÷ .
Definition: Synthetic division is a simplified method for dividing polynomials by monic linear divisors of the form x - c.
Example: Dividing 2x³ - 4x² + 7x - 11 by x + 2 using synthetic division: -2) 2 -4 7 -11 -4 16 -46 2 -8 23 -57 Answer: 2x² - 8x + 23 + 26/
Highlight: Synthetic division only works for monic linear divisors. For all other cases, algebraic long division must be used.
This page provides two examples of synthetic division to reinforce understanding of the technique.
Example:
- 3 0 -1 5 3 3 2 3 3 2 7 Answer: 3x² + 3x + 2 + 7/
Example: -3) 2 6 5 -3 -6 0 -15 2 0 5 -18 Answer: 2x² + 5 - 18/
These examples demonstrate the efficiency of synthetic division compared to traditional long division methods for polynomials.
Highlight: Synthetic division is a powerful tool for quickly dividing polynomials by linear factors, making it invaluable for solving polynomial equations and finding roots.
This section introduces the concept of synthetic division, a simplified method for dividing polynomials by linear factors. It begins by defining key terms and progresses to demonstrate the technique through examples.
Linear polynomials are defined as polynomials of the form ax + b, where a ≠ 0.
Example: 3x - 1, 2x - 5, and 3x - 1 are linear polynomials.
Monic polynomials are polynomials with a leading coefficient of 1.
Example: x³ + 5x² - 2x - 1, x² - 3x² - 2, and x + b are monic polynomials.
Monic linear polynomials are both linear and monic, taking the form x - c.
Example: x + 5, x - 2, and x + 3 are monic linear polynomials.
Highlight: All monic linear polynomials can be written as x - c, where c can be positive, negative, or zero.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀

THE QUIZES AND FLASHCARDS ARE SO USEFUL AND I LOVE THE SCHOOLGPT. IT ALSO IS LITREALLY LIKE CHATGPT BUT SMARTER!! HELPED ME WITH MY MASCARA PROBLEMS TOO!! AS WELL AS MY REAL SUBJECTS ! DUHHH 😍😁😲🤑💗✨🎀😮

This app is phenomenal down to the correct info and the various topics you can study! I greatly recommend it for people who struggle with procrastination and those who need homework help. It has been perfectly accurate for world 1 history as far as I’ve seen! Geometry too!
