Do you mean simplify or solve?
Is this the equation?
Now you can multiply both sides by
Multiply both sides by and you'll find , but can it?
the equation that i need to simplify first is ((x^2-1)^1/2 -(x^2-1)^-1/2 (2-x^2)) / (x^2-1)= 0
after i move the negative power, im not exactly sure what to do. I would multiply by the reciprical to get rid of the fration in the numerator but the 1/2 exponent makes things difficult. help is much appreciated!
