how do i show a radical? for now i'll use V to show the radical.
the problem is:
2x-2=1-V3-x (3-x is all under the radical)
My next steps: 2x-3=-V3-x
(2x-3)squared=(-V3-x)squared
2x-3)(2x-3)=3-x
4x squared-12x+9=3-x
4x squared-11x+6=0
then i used quadratic formula, and ended up with x=2, and x=3/4. I think it might be wrong though, can anyone figure out if i've got the right idea?
 
You did a wonderful job. It might have been a little easier to solve the quadratic equation by factoring, (4x - 3)(x-2) = 0 However, your method is just fine.

I forgot one detail. you need to check your results by substituting your answers into the original equation. You will find one works and the other does not.

Kim, show 'em like this:

square root of n : sqrt(n)
n squared : n^2

seems to be the "accepted/standard" when typing!
