Polynomial Basics:
1. Definition:
● A polynomial is a mathematical expression consisting of variables, coefficients,
and exponents, combined

Polynomial Fundamentals

A polynomial is an expression built from variables, coefficients, and non-negative integer exponents using addition, subtraction, and multiplication. The standard form looks like anxn+an1xn1+...+a1x+a0a_nx^n + a_{n-1}x^{n-1} + ... + a_1x + a_0, where the constants $a_n$ to $a_0$ are called coefficients.

The degree of a polynomial is the highest power of the variable. For example, in 3x22xy+53x^2 - 2xy + 5, the degree is 2. Each part separated by addition or subtraction is called a term, and the numerical factor in each term is its coefficient. The coefficient of the highest-degree term like the 3 in $3x^4 + 2x^2 - 7$ is the leading coefficient.

When adding or subtracting polynomials, you simply combine like terms. For instance, (3x2+4x7)+(2x2x+5)(3x^2 + 4x - 7) + (2x^2 - x + 5) gives you 5x2+3x25x^2 + 3x - 2. This works because terms with the same variables and exponents can be grouped together.

Quick Tip: When working with polynomials, always arrange terms in descending order of degree (highest power first). This makes operations easier and helps avoid mistakes!

Polynomial Operations and Theorems

Multiplying polynomials involves distributing each term from one polynomial to every term in the other. For example, (2x+3)(x4)=2x28x+3x12=2x25x12(2x + 3)(x - 4) = 2x^2 - 8x + 3x - 12 = 2x^2 - 5x - 12. You'll frequently use special product formulas like (a+b)2=a2+2ab+b2(a + b)^2 = a^2 + 2ab + b^2 and a2b2=(a+b)(ab)a^2 - b^2 = (a + b)(a - b) to multiply efficiently.

Factoring is the reverse of multiplication—expressing a polynomial as a product. For instance, x24x^2 - 4 factors as (x+2)(x2)(x + 2)(x - 2). This skill is crucial for solving polynomial equations and simplifying expressions.

Polynomials have several important theoretical properties. The Remainder Theorem states that when dividing a polynomial P(x)P(x) by a linear factor (xc)(x - c), the remainder equals P(c)P(c). The Factor Theorem builds on this: if P(c)=0P(c) = 0, then (xc)(x - c) is a factor of P(x)P(x).

Remember: The zeros or roots of a polynomial are the values that make the polynomial equal to zero. Finding these values is often your main goal when solving polynomial equations!

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.

Samantha Klich

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.

Anna

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!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

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!
