6x/(x^{2}+3)^{2}

3. The attempt at a solution

If I solve this function as a multiplication, i.e.

6x (x^{2}+3)^{-2}

my answer is

f ' (x)=[ (x-3)(x-1) ]/(x^{2}+3)^{3}

If I solve it as a fraction

f ' (x)=(v'g-g'v)/g^{2}

I get

f ' (x)=(x^{2}-1)/(x^{2}+3)^{3}

This is all so confusing. Please help me out. Thank you.
