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?

9x6^=25x-1?
You forgot the power -
Glad I never had to do anything like that.

ummm idk what that is right there....Originally posted by broncoFan! View Post
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....Comment

This some algebra 2 stuff.
Set one side to 0.
Plug the numbers into that formula.
Solve
End.Comment

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.Originally posted by 12and4 View Postsigpic
