Dude for real. I've been struggling in my class all semester and then I found this guy and now I feel like the Patriots did when they came back in Superbowl 51.
@@xxfisherxxdonut7858 you use this formula in calculus and other higher level math. And calculus is definitely used in the real world. You might not use the quad formula to directly solve a problem, but it’s part of a much bigger formula that’s used to solve something. And you can’t do higher level stuff without knowing the lower stuff too
YOU TOO!! LOL.. He gives us 2 examples.. we ask for another one, says " u gonna learn by doing" how in da world is that possible when u don't understand it at all. This vid is good enough for getting me started back
The only question we always ask our teachers. And the answer is that it doesn't solve anything but improves your decision making and processing/remembering of information, and applying information to other information (putting something together).
Reality, IT HAS NO USE IN EVERYDAY LIFE. However, this is the only subject that will help develop your logical thinking skills, ability of processing different scenarios and or data, develop decision making skills, making connections on different matter, and analyzation skills . Just like life, you tend to do this sort of skills everyday.
If you go into science or math you would totally use it though. www.quora.com/What-are-some-examples-of-real-life-uses-of-quadratic-equations sciencing.com/everyday-examples-situations-apply-quadratic-equations-10200.html plus.maths.org/content/101-uses-quadratic-equation-part-ii www.montereyinstitute.org/courses/Algebra1/COURSE_TEXT_RESOURCE/U10_L2_T1_text_container.html www.dummies.com/education/math/algebra/applying-quadratics-to-real-life-situations/ www.mathsisfun.com/algebra/quadratic-equation-real-world.html it's kind of a silly question actually
Alvin Mella i keep saying that after our teacher teaches us a new topic😂😂. That math like this isnt a use to everyday stuff. Its hard for people who wont be studying stuff with math. My future career is far from math😂. And math and other subjects can fail a person whose goal doesnt revolve around these stuff😂😂😂
Same! My teacher literally yells into the speaker during zoom and on the lowest volume my ears bleed lol. So i’ve resorted to simply watching tutorials online.
When you don’t play attention in class so now you gotta find a TH-cam video to help you cause if you don’t you’ll fail and won’t get the credit to graduate and then you’ll be homeless and can’t get a job all because you can’t do the quadratic formula 🙂
Thank you so much, there's only one tutor at my school and she doesn't care about the students at all, she especially doesn't like me since I'm slow to pick up some things. Thank you!!
Study pug is actually amazing, it helped so much but its like $25 a month, i guess its worth it because they break it down like a tutor, and it would cost more to have a tutor idk
Thank you so much, I done this in year 10 for the first time today and my brain was all over the place but now I understand it. Thanks again. Subbed 👏🏾
Can I ask questions? How to identify the values of a, b, and c on this quadratic equation 1. x²-x+3=4x²-5 2. x+3=(2-x)² 3. 3x(2+2x)=x(5x-5) 4. 2x²+x(x-2)=7 Thank you for answering this questions.
you'll need to simplify and change them so that they are in the form of ax+bx+c=0. if you can't, then there are other ways to factorise and expand and simplify those.
FINALLY! I've been looking everywhere for a video that explains how to simplify complex squares at the end. Kahn Academy actually messed up and then didn't explain it lol. THANK YOU!!
It can be solved in an easier manner. 2x^2 + 2x - 5=0 Lets write the coefficient of each term of the quadratic equation such as a = 2(coefficient of x2) , b= 2 and c= -5 Now , D = b2 -4ac i.e. D = 44 Since , D > 0 Therefore, The given equation has real roots. Then, √D = √44 = 2√11 Now , Using the quadratic formula We can get the answer
wow this is very impressive vid. I found the question you presented hard but the way you explained it, threw all those troubles away, i even learn't something knew!
This is a good video, but how would I go about creating a parabola for this equation? Can I just replace the 0 with y to find a y-intercept, vertex, and axis of symmetry? If not, could someone please explain how I would?
Am I the only one who's studying this over the summer, before starting Algebra 1 in the fall? Probably, but I'm only in eighth grade, and I want to be prepared. Wish me luck!
***** Thank you for your comment, Prince Rhem it is very kind and considerate. It is completely accurate and does describe me perfectly. Why, you should get an award for the immense thought process it must take to come up with such a poetic, empathetic thing to share with a fellow person.
***** I don't really think that this is spam (considering some of the bull that most people will post in the comment section of anything), but thank you for that, I guess.
So we have this higher math in 7th grade for the smart math kids so I have always liked math and this helped a lot. They are learning this now but I want to catch up to them since my math is a bit too easy rn
An example of an algebraic expression is 5x + 6. Here 5 and 6 are fixed numbers and x is a variable. Further, the variables can be simple variables using alphabets like x, y, z or can have complex variables like x2, x3, xn, xy, x2y, etc.

Thanks this is easy as balls you unlike other people on the internet don't give examples of how to solve the problem
my math teacher requires us to distribute the +/- sign to the rest of the equation, to come out with 2 final answers
Dude sameeeee
Alex Fisher that must suck
Alex Fisher that's good practice because it gives you the two x intercepts that you use when graphing the quadratic formula
Your right alex you must distribute the positive and negative sign it's a rule

thanks a lot brother for your help
in fact, i understand you more than my teacher in school

2x^2 + 2x - 5=0
Lets write the coefficient of each term of the quadratic equation such as a = 2(coefficient of x2) , b= 2 and c= -5
Now , D = b2 -4ac
i.e. D = 44
Since , D > 0
Therefore, The given equation has real roots.
Then, √D = √44 = 2√11
Now , Using the quadratic formula We can get the answer
