    First factor out the 1/sqrt(x^2+2).

    This should leave you with (1/sqrt(x^2+2))(x^2 + 2 + 8) which simplifies to (x^2+10)/(x^2+2)^1/2

    I followed through. Put the answer into my online homework and it came up as incorrect.

    ok yeah I get (x^2 + 10 )/sqrt(x^2+2) and i don't know where to go from there....
