  • Quadratic Equation

    Could someone help me solve this quadratic equation? It's on my hw and I can't really figure it out. They want me to solve this using the quadratic formula. 9x6^=25x-1. How do I even set this up in a Quadratic formula method?

    You forgot the power

        ummm idk what that is right there....

        9*6^=25x-1????

        9x^6=25x-1???

        9x^2=25x-1???


        set it up by putting everything on one side, equaling it all to 0...


        so if it really were the third one....


        9x^2-25x+1 = 0....


        then you'd use the formula


        (25 +or- sqrt(25^2-4*9*1))/18


        do the calculation for plus and for minus and you get both the roots....

          oops my bad. On my calc that automatically means to the 2nd. Sorry I assumed most people knew that.

            This some algebra 2 stuff.

            Set one side to 0.



            Plug the numbers into that formula.

            Solve

            End.

                      Yeah actually that seems about right. I remember learning about it in middle school now that I think about it.

                              Yeah, but I have a minor headache right now and all those #'s certainly don't help. "Put everything on one side" Works a lot better in my view. Thanks for trying though but I'm more of a words person over #'s.
