    I'm in algebra 2 and my teacher doesn't explain any of this. He shows us him doing a problem and then we're given an assignment. Watching these videos are such a big help.

      This is early Algebra I. If it is coming up in an Algebra II class then it is likely just basic revision before moving on to proper Algebra II topics.

    12:15 I just now realized what factoring really is and what it can be used for. Factoring is rewriting a number or expression so that it is the product of multiplication. And one reason for doing this is so you can cancel out terms in a fraction in order to quickly simplify it. You cannot cancel common terms between the numerator and denominator if there is addition or subtraction involved between any of the terms, so factoring it makes everything the product of multiplication instead of addition / subtraction, which then allows you to cancel terms. I really love when things start coming together and everything becomes clearer.

      When I first started learning Algebra, which was only about a week ago. This is the first question I asked when something didn't make sense to me:
      "I was watching a video that says 9x + 3 / 12x + 4 can be simplified to 3/4. But can't just 9x / 12x be simplified to 3/4? Can't 9x + 3 / 12x + 3 also be simplified to 3/4? How can they all be the same thing when they are clearly not the same thing? I understand how 9x / 12x and 9x + 3 / 12x + 4 are the same thing. But what about 9x + 3 / 12x + 3? Isn't that also 3/4? Since don't the + 3's on each one cancel each other out?
      "
      Do you see at the end where I said, "Don't the 3's cancel out?" And they don't because they are being added to the other terms not multiplied.

      Something else I just realized, too. When you flip terms that are being added or subtracted by multiplying by -1 you are simply factoring it! I was wondering where you get the -1 from. But all you are doing is finding a way to make it the product of multiplication. It's like taking a single number 12 and rewriting it as 3(4). Where did you get the 3 and 4 from? You simply made 12 the product of multiplication by using its factors! THAT'S WHY THEY CALL IT FACTORING, JASON! I HOPE YOU LEARNED SOMETHING NEW TODAY. :)

    I just want to thank you for your series, as a senior going back to school to get my grade11; 12 algebra, you,ve been a blessing, as on line books don't explain anything. I found you late in my grade 11 class, happy to say I passed not the mark I wanted but it's still a pass and I continue with you in grade 12. these classes are fast 2 years into 1, talking about math I never knew existed could not relate until I started watching you. Again thank you sooooo much, I am sure many others appreciate your dedication, time and knowledge to help others 😊 thank you 👏👏👏👏

    It's helps so much that you rewrite the problem before cancelling, other videos look so complicated when they do it all on top of the original problem.

    Great lecture. If only there were more professors like you, especially for math and sciences. There is an interesting point I never thought of until now. Maybe you could've used the example with s^2-t^2/(s-t)^2 to show explicitly that (s-t)^2=(t-s)^2 which is pretty convenient to keep in mind when solving similar equations because such manipulation makes the process faster.

    Jason, (or anyone) On the problem just before the last 31:08 with the result: x-2/x-4, why wouldn't you further factor x-4 as a difference of squares? Factoring as: (√x+2)(√x-2). Is there rationale for no longer factoring when factoring further is possible? In general does one stop factoring when no cancellations will result? Any insight is appreciated.

    • @gtlasers1
      @gtlasers1 5 місяців тому

      factoring further when no cancellations are possible isn't needed for simplifying rational expressions. Once you've factored to the point where no further simplifications or cancellations can occur, you've done enough and none else is needed.
      The expression
      x-2/x-4 does not have any common factors to cancel out, so it's considered fully simplified. Factoring x−4 into √ ( 𝑥 + 2 ) √ ( x ​ +2)
      wouldn't help because it isn't a good factorization for non-perfect square X. In summary, additional factoring is not required if it doesn't lead to cancellations or simplifications of the origin equation.
