2 x^2  1/x^2 = 0 ???
2 x^4 = 1
x^4 = 1/2
x^2 = (1/2)^.5 or (1/2)^.5
x = (1/2)^.25 or (1/2)^.25 or i(1/2)^.25 or i(1/2)^.25
thank you.i am trying to sove for critical numbers. the book is giving me an answer of
x=+square root 2/2

I am wondering if the problem then is this:
(2x^21)/x^2=0
2x^2=1
x= + sqrt (1/2)
but of course, multiplying that by sqrt(2/2) one gets
x= + sqrt (2/4)= + .5 sqrt 2
