calculating rocket trajectories like i'm trying to do with potassium nitrate and sucrose motor rockets, also plotting things in finance which is literally everywhere, and a lot of other applications
This video requires more explaination in the places like where 7X(X+1)+2(X+1) becomes (7X+2)(X+1) (The math adds up, I just don't know how you got this answer) Or how the X went in front of (X+4)^2(X+4) Just a little more explaining so that listeners will fully understand factoring rules. The last problem is evil. lol
tbh i dont know why im replying a yr later but thats because you dont write the pronlems down and solve them with him look for a different problem online and hey follow his steps
I usually understand your vids but this one rlly confused me and I just learned how to add and subtract rational expressions so its not that I am missing info its just this vid couldnt make the connection
I have a question? Can't the answer be just x+4 / x+1? ,,,, my answer is like this when i didnt have to do the inverse , i just divided it then cancellation
What is the meaning of "2 numbers multiplied equal 14"...that part has confused me. I would really appreciate the insight as it is some kind of trick. I factored without it but it was most likely harder as I used trial and error. Anyone can help?
So A + B = 0 would be like 5+ -5 =0 Since it cannot equal 0. He move the A over to the other side of the Equal sign the same as you would move any variable. 2x = 10. Divide both sides by 2 to get x = 5. In this case subtract B from both sides to get: A = 0 + -b or A = -B with no matter how you switch them, it will always be 0. Since the Denominator cannot be 0 in a fraction, A, does not equal -B (or else they'd cancel out to zero) A =/= -B.
we are all human. he's allowed to make mistakes. it also helps to show mistakes that students often make when doing the problems themselves. its actually good, it helps us to spot potential mistakes.
When you realize that mathematics as a whole hasn’t given humanity a single thing besides cellphones, capitalism, and ever other horror of the modern age. Makes me really love learning about these concepts 😊
Thanks had to rewatch many times because of the multiple breaks I had to take to cry.
i have no idea what im doing.
nobody does
All I want to know is how would I use this in real life.
NoseyMold Teaching math, engineering, physics, etc
NoseyMold Or even making UA-cam vids that teach other people how to do it while you make money
So basically, no where. That's kinda like saying, "Teach everyone how to play an instrument because some of them will be musicians."

When all you need to graduate is to pass math .... UGH!!!! 😭😭😭😭
suzette8711 I'm in the same boat
i’m in that boat right now and i’m struggling so much
I DONT UNDERSTAND WHAT YOU'VE JUST DONE

about to throw up all over myself so i can go home and not take this test in an hour. this is so disrespectful.
how did it go?
@@opmriotyy8489 im sure i failed but. i graduated years ago and that’s all that matters 😂😂😂 thanks for checking.
@@hashtagirenis lol, I just love replying to comments that are 5+ years old and seeing if people respond.
@@opmriotyy8489 luckily i wasn’t dead or something. thanks for checking in 💀
@@opmriotyy8489 as do I
Wat the he'll is he doing
I prefer to Divide and then conquer
Thanks for the tut
Nice. What did you use to write the solutions?
I STILL DONT FUCKING GET IT!!!! IVE RE WATCHED THIS VIDEO 12 TIMES!!!!!

all i heard was A B a bee a B A bee aye bee aye B
if this guy repeats something one more time I'm punching my computer
Yan Wang i agree i agree
Better tape your knuckles watching Sal Kahn then...

Thank for this video, I have a learn😇☺
what program do you use to teach here?
My teacher does not want us to do the whole ( a + b = #) Thing . she just wants us to factor it. I find it easier just to go straight to that.
I love the typo part

Jimmy Munoz factor by grouping
Dude you are more difficult than my school math teacher.
Why can't A= -B ? Any one answer this please? If there is a lesson online that teaches this please let me know... Thanks
So A + B = 0 would be like 5+ -5 =0 Since it cannot equal 0. He move the A over to the other side of the Equal sign the same as you would move any variable. 2x = 10. Divide both sides by 2 to get x = 5.
In this case subtract B from both sides to get: A = 0 + -b or A = -B with no matter how you switch them, it will always be 0. Since the Denominator cannot be 0 in a fraction, A, does not equal -B (or else they'd cancel out to zero) A =/= -B.
i went ahead and did the problem just to find out that you make a typo.....
Lol
same!!
final tomorrow! thanks!!!
Did you pass
why wouldn't you cancel them out first? couldn't you simplify the problem then multiply across?

First of all, even if the question is difficult, I will understand if I look again
Everybody subscribe to "the Organic Chemistry tutor". He makes math 10 times much more understandable.
wtf. why can't I watch the vids???? Is there a charge now??

Are you being sarcastic?
me too ><
@milkymallowxs08 Ow my bad x+4/ x(x+1)
Whyyyyyyy????
It is how you factor trinomials. /watch?v=GMoqg_s4Dl4
Well….I am FAILING!!!
math hurts me
First a hard
Yes I totally do not understand.
Jealous teacher alert.
i hate math
@Mark Mungrove - My college professor makes the exact same kind of errors. It happens. Your critique of his work is childish and ignorant.
talks in circles no help AT ALL!!!!!!!
