....... Thank you so so so much for making a series on Rational expressions. I have a test on this tomorrow and since I missed out a day, I didn't understand anything but watching your videos really made me understand how to solve each and every problem that I get. Because of you, I don't have to worry about failing the test tomorrow.
One great thing about mathematics is that videos explaining how to work equations out, for the most part don't become outdated. Thank you for posting this some 9 years ago :-)
Now thats what i call a math teacher ! Well my teacher is great too but i think im not paying attention in class! Thanks i learned a lot!! Got to pass my exam today!
My parents are most likely wondering why I'm silently screaming in victorious mood defining tones.... I'll tell them later. Right now, I'M GONNA PASS ALGEBRA!!! Thank you, patrickJMT!!
Thanks you saved my guts! (And that people is how you get a a quick, step by step explanation on an assignment on a topic which is completely new to you and score high on it without bothering to attend the actual class!!! XD )
i just notice ur using my fave marker "Sharpie" oemge thnx for the video..our teacher incourages us to watch video like this to understand the lesson more..aish
why does in your previous video of addition and subtraction of rational expressions, you didn't multiply the denominator of 5x^2 + 2x which is (x+2)(x-6)?
I have been getting D in algebra because i couldn't do my HW because i just had no idea what to do. My teacher is a nice lady but cant really teach me. Thank you so much for creating this channel. New subscriber. P.S. I have the problem 5/3n-2/2n m not sure what to do. Plase help :)
Funny how nice people around the world make short videos and post them online on how to do math for example, and they're wayyy better teachers than some of ours. they teach it faster and they don't get paid for it. If i had to name the problem, id say seniority. Some of my teachers at my school have been there for awhile so even if they're getting poor results they don't get fired and younger teachers who are more connected to us don't get hired.
Timothy Russell it can’t, if it has a whole number it’s not a rational expression anymore. Rational expression is basically fractions with letters without whole numbers.
You don't have to do that, I'm sure your teacher would want it as (x+8) (x-8)..His simplification wasn't right. You can still simplify x^2 - 64..So basically, don't put it back, just leave it as it is.
Reighlene Farmer it's called Difference of two squares. The exponent is two and it's divisible by two, then it's a perfect square, also the 64 the square root of that is 8. (x+8)(x-8). If you times them, it'll be x^2 - 64.
why did he put it back to x^2 - 64 though it should be simplified? i'm confused :( should we really put it back or not? :(( but i get it how the process is. :) thanks
