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
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 😊
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.
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?
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
