Solving Quadratics by Factoring and GraphingI would very much appreciate the help on checking if these are correct "The thing about quotes on the Internet is you cannot confirm their validity" ~Abraham Lincoln #2 20121211 16:22:51
Re: Solving Quadratics by Factoring and GraphingHi;
Missing an x.
That is incorrect. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20121211 20:18:44

Re: Solving Quadratics by Factoring and GraphingYour teacher is not correct but if he/she wants to say you are right then let's leave it alone for now.
The correct equation is, In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #9 20121212 18:23:12
Re: Solving Quadratics by Factoring and GraphingAlright, let me try that my self and please do tell any mistakes I make along the way. I will also try #15. "The thing about quotes on the Internet is you cannot confirm their validity" ~Abraham Lincoln #11 20121212 21:35:41
Re: Solving Quadratics by Factoring and GraphingMy class shows me how to do #15, this website shows the exact same thing: since I can't post links, search on Google: Using Quadratic Formula to Find the Zeros of a Polynomial and click the first link.

Re: Solving Quadratics by Factoring and GraphingHi; as you said? You know that neither of those answers make any sense. How could the ball hit the ground in 1 second? So either you picked the wrong equation or you did not solve it correctly. Answers in math ought to make sense. Mine don't but that is only because I work on nonsense.

Re: Solving Quadratics by Factoring and Graphing
Sorry, that is the one I meant. The equation is right but the roots are obviously not. Like I said the ball can not possibly hit the ground in one second so you know something is wrong. The quadratic formula can be a little tricky. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.
