Homework Help: Quadratic Equations

Posted by Emily on Wednesday, February 7, 2007 at 10:50pm.

Ok, I am supposed to find out what the variables are by factoring and finding square roots. I couldn't find the right factors of a and c that added up to b in the equation (did that make sense?). Please help me find them! TYVM

-5n+6n^2-4=0

6y^2+12y+13=2y^2+4 simplified is:
4y^2+12y+9=0.

I know the answer to the second equation is -3/2, so I know it is a binomial square we are dealing with. Plz help, any help is greatly appreciated!


-5n+6n^2-4=0 or
6n^2-5n-4=0 does it factor to
(3n -4)(2n+ 1)

4y^2+12y+9=0.
(2y+3)^2

The first equation is -5n+6n^2-4, not 6n^2-5n-4=0. Thnx for all your help!!
