Hello, deviantxane!
Where did this equation come from?
Are you sure it's correct?
Note that
We have: .
Multiply by
Square both sides: .
Quadratic Formula: .
For a real root: .
although technically I am working on a calculus problem the problem I'm having is with algebra. a step in my problem requires me to factor this equation:
4x-2(x^2-1)^-1/2=0
I just end up going in circles even if I simplify it and use the quadratic formula. help would be much appreciated.
