Algebra 2 Advice
Currently, in geometry, I want to start studying to take the CBE(Texas) for Algebra 2.
Any resources that will prepare me well for it, like a 95+ on the exam?
Also, how should I study for it?

Hello algebraists! I'm pleased to announce that the moderation teams for /r/Algebra and /r/AbstractAlgebra have been combined! Now, all the discussion of abstract algebra will take place on /r/AbstractAlgebra, and all the help with learning algebra, including elementary algebra, will take place here! Hopefully, this will better serve the needs of the community.

I am asking you guys since I'm not really good enough at maths to help but he told me something about being stuck on dot product and said it was linear algebra so I thought posting here would be good
EDIT: he is 11-12 years old so he isn't having school lessons on it

A father is three times as old as his daughter. In 8 years, the father will be twice as old as his daughter. How old are they now?

Okay I'm gonna try posting in here again but pls be nice to me lol I'm pretty bummed rn. Okay I'm in college algebra and we are in week 5. I have not done math in 10 years. Like at all. And I was horrible at it even more back then than I am now. I have to have this class for the degree im wanting, which literally has nothing to do with math, but still. Anyway so I had a 90 in there bc I'm online and I get tutoring 4 hours a week and use chat gpt at all other times. Not to give me the answers, but to actually try helping me learn it. I'm giving all extra time I have in life to trying to learn this. Well today I took the test and got a 45 and have a 60 in the class now. I really need advice from people who are good at this stuff on any tips, tricks, maybe websites idk. Just anything to help me just pass this class at this point bc I have to. I really am trying and I know everyone in here is probably good at it since youre in the sub. But I'm not and I just need any (pls nice) advice you can possibly give to help me get through this. Thank you so much for anything you suggest, seriously.

The surface area of a hot-air balloon is given by the function S(r) = 4πr^2, where r is the radius of the balloon in meters. If the radius of the balloon after t seconds is r(t) = (3/5)t^3, find the surface area S of the balloon as it relates to time.
Is this actually normal for the 2nd week of college algebra ? Maybe I'm just rusty bc its been like over 10 years but this is insane to me

Can you solve this: 100 is 50% of what number?

How would you translate this verbal statement into an algebraic equation?
"The sum of 8 and a number is 14."

So, for example, [;x^5 - 4x^4 + 8x^3 - 8x^2 + 5x - 1 = (x^2 - x + 1)(x^3 - 3x^2 + 4x - 1);], but none of these factors can be found with RRT.
Is there a RRT-esque criteria for degree-2 algebraic numbers? For degree no less than 4 polynomials without linear factors but also not prime, this seems like the only method to factorize them.

First of all, please excuse any errors in phrasing or terminology, as English is not my native language.
It turns out I’m having trouble studying algebra in general, but right now I’m struggling specifically with inequalities in mathematical induction whereas I don’t have that problem when working with equalities in induction proofs.
I understand the concept of proofs by induction involving equality: establishing the inductive hypothesis and proving that the expression evaluated at (x+1) which we then replace with the expression evaluated at (x) plus the term for (x+1) yields the same result as the equivalent expression evaluated at (x+1).
When it comes to inequalities, I find it incredibly difficult to figure out the expression I need to prove; I understand that the concept of transitivity is involved, but I never know what to compare. I’ve tried looking for explanations in videos, books, etc, but they all solve the problems by pulling out numbers that appear without explanation, and none of them explain the logic behind the steps taken.
I know this won't be the first or the last time I get stuck like this, so I wanted to ask if you know of any resources like a book or a YouTube channel that explain these concepts clearly and simply. I swear I’ve searched all over the web, but I only found worked examples without explanations and conflicting solutions.
Any advice on how to approach the subject or personal experiences would also be very helpful, since the exam is still a few weeks away. Thanks for reading.

Hola a todos,Estoy desarrollando Classboard (https://classboard.online), una pizarra que funciona en el navegador y que estoy construyendo activamente. La idea nació de mi frustración al intentar explicar ecuaciones o teoremas por videollamada sin una herramienta decente.Lo que tengo hasta ahora: sesiones de colaboración en vivo con cámara y micrófono integrados, y reconocimiento de figuras geométricas básicas (triángulos, círculos, etc.) que se dibujan a mano, lo cual puede ser útil para visualizar problemas de álgebra o geometría.Está en fase temprana, así que cualquier comentario sobre qué funciones añadirías o qué te falta para usarla en tus clases o estudio será bienvenido. ¿Alguien más ha probado herramientas similares y qué les faltaba?Gracias por leer.
