**Reiny**, Saturday, February 18, 2012 at 7:34amcarefully use the quotient rule

f'(x) = [ (x^2+x+1)^(1/2) (2) - (1/2)(x^2 + x + 1)^(-1/2) (2x+1)(2x) ]/(x^2 + x + 1)

= [ (x^2+x+1)^(1/2) (2) - (x^2 + x + 1)^(-1/2) (2x+1)(x) ]/(x^2 + x + 1)

= (x^2+x+1)^(-1/2) [ 2(x^2+x+1) - x(2x+1) ] / (x^2+x+1)

= (x+2)/(x^2+x+1)^(3/2)
