THES JUST NUMBAS. THEY AINT HURT NOBODY

[@donnasmith9501]

I did high school algebra 50 years ago and now have decided to get my accounting degree. Algebra has changed a lot since then..Thank you for your help. I'm so glad I found you guys. I already passed fundamental math with your help and I'm half way through Algebra..My head spins but the way you teach is really, really helpful. Thank you Mr Witt!!!

[@FortBendTutoring]

I'm very proud of you Donna! I truly value the effort you're putting into completing your degree! Good luck 2 you and keep excelling in your endeavors!

[@donnasmith9501]

thank you, you guys have really helped with the math part..in that, you're my new best friend!!

[@safehaven9014]

I like the way he said, "Remember, this is just numbers. They can hurt nobody." Thanks Mr. Witt. I somehow like math because you made me understand every single shit. I'm happy to say that I'm already not spending any tears just to understand and process what my math teacher's saying every time we're having a class. Thanks a lot.

[@FortBendTutoring]

My pleasure Safe Haven! Thanks 4 the feedback and support! 😁

[@jomimi1225]

[@alisque433]

OH MY GOODNESS! THESE VIDEOS REGARDING RATIONAL EXPRESSIONS HELPED ME SOOO MUCH! Thank you Mr. Whitt!! My teacher can't teach very well and I finally understood it! It's my exams tomorrow so I'm currently cramming. Thank you for these videos! 😭

[@FortBendTutoring]

+Donut CAKE 03 My pleasure! Good luck on your exams tomorrow! I'm rooting 4 you!

[@Katz93065]

Great Lesson! I like how you rewrote the fraction, factored out the -1, ultimately changing the problem to work. Thank you.

[@angelaclarke2127]

Happy 2 help Ryouta! Thanks 4 watching!

[@FortBendTutoring]

Thanks! I figured that would be a neat technique to include in the video. Glad it was helpful!

[@carnivalwrestler]

You cover so much in so little time, and yet, you make everything so clear, easy to grasp, and easy to retain. From the comments I read, it seems that this is not happening in our schools, and I wonder why. Maybe some math teachers need to watch your videos. They could make a math pedagogy course for teachers from your vids and put it into their state certification requirements for math teachers. Just a thought.

[@FortBendTutoring]

Wow! Huge compliment! Thanks 4 your thoughts and kind words CarnivalWrestler! Obviously there’s God-given talent, expertise and experience involved in creating each video (not trying to come off as bragging, but blessed), but I create each video as how I would want to be taught. Coming from that angle it really simplifies the process. 👨🏾‍🏫😁

[@lenniejoaquin7091]

Im quite confused in 7:48. How did it end up being (4x+4-3x'-3x)?

[@sugakoushisenpai]

How did you get 4x-4 at 7:41 ?

[@FortBendTutoring]

I multiplied the binomials in the numerator. Here’s a video 2 help with that process: Multiplying Binomials: The Distributive Property and FOIL Method [fbt] kzbin.info/www/bejne/npS8iqCmiq6dh7M

[@leaguegamer9182]

on your 4th example on the last part it's confusing me is it really positive 12 negative 6 is equal to positive 6 sorry for my bad english

[@FortBendTutoring]

Yes, 12 - 6 = 6.

[@dennissalas727]

I really love this. I always watch your video everytime I have a difficult understanding in RAE. Honestly when my teacher discussed about this I really got a tough time. It sucks. I mean to be honest I like math, love to be exact but not in all times math is easy. It gets harder and harder when we get older. But RAE maybe the hardest topic I've ever encountered in life. Like really. But so I realized its not. It takes time to realize that math is easy if you do put a effort to study. So thank u very much for this.. I really appreciate. I really do.

Mr Whitt, you’re good but dang, I have to eat, get some sleep and come back to this topic

[@nalihewage]

Mr. Whitt, why did u add the minus to the 1st denominator? can't you do it to the second? please explain.. Thank you for helping.

[@FortBendTutoring]

It was to get common denominators. You could do it to the 2nd denominator instead of the 1st to work out the problem.

[@a.koolinallday364]

where did the -pq come from when you factored the numerator

[@FortBendTutoring]

The -pq is part of the factoring pattern for a sum of cubes. Check out our video "Factoring: Sum of Cubes". kzbin.info/www/bejne/i2qcZ4Nuf8aFrqs

[@raygodinez1501]

Mr Whit is there a way quick way (or test) to find out if a certain equation cannot be factored? Thanks sooo much for your lessons. They are a Godsend!

[@FortBendTutoring]

You can use the "general strategy" for factoring which just analyzing the equation/expression to see if can be factored using any method. kzbin.info/www/bejne/jYKVpqSposajgtk

[@hubbiemid6209]

Fort Bend Tutoring Thank you for the very quick response. Adding and subtractions these expressions weren't as easy I thought. ur vids helped a lot :)

[@lykaabregana7174]

Mr. Whitt, why didn't you factor out the numerators of both terms first since they can be factored out by gcf?

[@FortBendTutoring]

+Lyka Abregana Our goal is to add the expressions, so focus on that task first. After finding the sum you can then attempt to simplify, if possible.

[@lykaabregana7174]

oh i get it now, thanks a lot! :)

[@outsmart6931]

ey fort bend tutoring could you help me in my problem...I wanna solve m squared over m + n plus 2mn + n squared over m + n.... what should I do with the first numerator which is raised by squared tnx

[@FortBendTutoring]

Just add the numerators and list the terms in descending order of m so that the numerator is m² + 2mn + n² over m + n. Then, factor the numerator and simplify.

[@victoriadeleon6791]

How would you do if you have 3 terms?

[@FortBendTutoring]

Same process. Find the common denominator and make equivalent fractions. Then, combine the numerators and simplify.

[@kirsten6651]

How did you get x-1?

[@kirsten6651]

on 11:27

[@FortBendTutoring]

I’m rewriting the first term as an equivalent fraction. Comparing the original factored denominator with the LCD I’m missing a (x - 1). Therefore, I multiply the numerator and denominator by (x - 1) in order to create an equivalent fraction which can combine with the second term.

[@neonspectreyt4577]

Them: hearing Q Cube Me: Hearing QQ

[@sanzidaamin4993]

Mr. Whitt, why did you distribute instead of canceling?

[@sanzidaamin4993]

At 7:34

[@FortBendTutoring]

You can only cancel when everything is being multiplied or divided (multiple factors divided by multiple factors). Since we had multiple terms in the numerator, you want to distribute to combine like terms before simplifying.

[@Oliver-js7it]

OMG the intro 😂😂😂😂

[@lykaabregana7174]

Mr. Whitt, in the 3rd or 4th problem i think (i forgot) we can still factor -3x^2+3x+2, the factored answer is (3x+2)(x+1) and we can cancel out the (x+1) in the denominator: (x+2)(x+1)(x-1), why didn''t you?

[@lykaabregana7174]

can you not factor expressions which all the terms are positive?

[@FortBendTutoring]

+Lyka Abregana That expression is not factorable. Try multiplying your result.

[@FortBendTutoring]

+Lyka Abregana There are many expressions that have all positive terms that are factorable.

[@stephanied.5709]

I don't get it. :( the part when you distributed 2 to (x-1) in number 2. How did you get 2x-2+4x+4-3x^2-3x

[@FortBendTutoring]

+Stephanie Domingo I used the methods shown in this video: kzbin.info/www/bejne/npS8iqCmiq6dh7M

[@stephanied.5709]

Fort Bend Tutoring Thank Youu so muchh :))

[@jeremiahdeanvitug8537]

why did you not divide out and why did you distribute.......... in question number 3

[@FortBendTutoring]

Depending on the step you're referring to, dividing out takes back to a previous step. The process is the same as adding fractions with numbers. You must first identify a common denominator and then create equivalent fractions using that common denominator. We distribute during the process to help us combine like terms when we add the numerators.

[@JD-ez8fg]

Mr. Whitt,why put ( ) a round 4-3x and not on the 2

[@FortBendTutoring]

It’s because it has multiple terms, two in this case, and I’m ensuring the next step is setup correctly. (4-3x)(x+1) and 4 - 3x(x+1) are not the same while 2(x-1) and (2)(x-1) are the same value. So you can always put parentheses around both, but sometimes you don’t have to depending on the expression (for instance, when multiplying one term times two terms).

[@BBQPitmaster626]

I don’t get how you factored the numerator considering that they are not the same variable. It went a little too fast for me.
