Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

Still don't fully understand, but this was more helpful then my teacher

[gera]

I got my staar test tmr and these videos are for sure gonna save me

[MisterEMixez]

Until now I really didn't get it, but this video broke it down to the essentials. I find that some teachers expect us to understand more than we do and take for granted that this makes sense to everyone.

[kingtyronsuayan]

For me this video is very helpful and I can understand it clearly.

[sophiakim]

I have a question: so basically the x with the least value is it? Like you did x to the power of two and that was the least

[cheesecakevanila]

i understood the last part of how we would do it in the future than all that gibberish, i dont know why

[justcallmerei]

Way more helpful than my teacher, usually get straight A's but I got an 80 here, the lowest B manageable, hope my grades rise a little by the end of quarter 1

[ryanoh]

this went a little fast and the extra steps made it more confusing

[justinmaduako]

((Good afternoon, Mr. Khan, my class 'N I did the worksheet about the polynomials 'N factoring, earlier today (🏫👩🏿‍🏫👨‍🏫➕➖✖➗🟰🔢📖📕📔📚📝✏💯❤⭐))).



From, Justin Maduako

I don't think the superfluous steps in the beginning are really that helpful in explaining it. It just makes the problem unnecessarily convoluted

[uni-teven]

14th I guess, 6 years later. Btw nice vid :D Thanks for this K.A :)

[LoganTysdal]

If I'm ever sick or gone from school, I come to this channel not my teacher's website

[parishayaasif]

can you plz factorize this polynomial X^2 - 14X + 49

[yearoldwhiteboy]

uhh okay ill try not to get scared by the comments but thanks for the vid

[amichaeel]

This example is way too easy for it to be helpful

[Chris-nkmq]

what if there is an extra variable at the bottom

[renees]

10 years later, well I am still in school though

[brob]

ayo what if the numbers cant be factored down

[AsherSmithFilms]

I understood it, but then you confused me at the very end by going to fast.
