Almost- you dropped a "-" and left a "4x". It should be 4(x^2+ 2)[(x^2+2)- 4x^2]/(x^2+ 2)^4

Then i gotta set it all to 0[/QUOTE]
Once you have set it equal to 0, you can immediately multiply through by that (4x^2+ 2)^4 in the denominator and get rid of it- a fraction is equal to 0 if and only if the numerator is equal to 0.
