Excuse me, what do I do if one of my sets of points has a 0? for example (0,4).

@vlogtomejr.1919

7 жыл бұрын

In your case, (0,4) is the y-intercept. Therefore, c=4. Still unsure? Plug it in! f(0)=ax^2+bx+c. Substitute every instance of x with 0. a(0^2)+b*0+c. What's left after this is c. Since f(0)=4 and f(0)=c, then c=4

Helped me get an A thank you so much

At 3:08 what he did there was multiply the bottom equation by -1, and that is allowed, and what you get for your trouble is all the signs change and the coefficients on the C terms are now opposites or additive inverses.

nicely done, but what about when you can't reduce when you're trying to eliminate a or b. is it protocol to multiply each equation by a different value to achieve the same a or b value?

@danielschaben

9 ай бұрын

If we use the method of elimination, then yes we multiply the two equation by the the number required to make the least common multiple of either a or b

why did you at 5 minutes and 15 seconds say to multiply the bottom equation by 3. Where did you get the 3 from thanks.

@danielschaben

11 ай бұрын

I multiplied by 3 to match up the variable b in both equations. So then both bs would have a 3 coefficient. The process is the key to eliminating the b variable. If the top equation had a 4b, I would have multiplied by 4.

It's the exact same answer if you do a quadratic regression, and it saves a lot of time! But I did enjoy learning this method!

This is probably a stupid question but does it work with any three random points?

@danielschaben

5 жыл бұрын

Actually that is an amazing question, and one I have had in the back of my mind, but never spent time exploring. It won't work with any three points because the three points have to form a parabola. So if you used (2,1) (2, 3) (5,7) for instance y = ax^2+bx+c would not work however I think x = ay^2 + by + c would work for those three points. You have me thinking. ... Great question. If you stacked three points it would not work in either case (2, 1) (2, 3,) (2, 4). would not work, or any three collinear points would not work. I don't have time right now to explore much more. But what if the three points lie on a circle? What about three points that lie on a hyperbola or trig function? ohhhh so much we could explore with this seemingly silly question. Good work getting my mind working!

Nice, looking back, the top equation could have been reduced by 3 to simplify even further.

god bless you but what happens if I get numbers such as 0.55? Because your tutorial works bad at this case A (-2/22) B (1/7) C (3/2) and at the end, my results are a bit different than the 3 given points like if I use B I get 6.98 instead of 7 or 22,87 instead of 22

I love watching different instructors/teachers/professors show the steps in working more complicated algebra topics but I wonder if too much time is spent on the basic arithmetic. If someone is learning algebra and doesn’t get eliminating or moving variables and constants in the solution process then maybe they should be watching basic math videos first. It really slows down the instruction. Just an observation.
