    Find inflection point(s) of the function

    f(x)= x/(5x^2+5)

    I found f''(x) which is required to solve for x, but I still get the answer wrong on my online hw. what i got for:

    f''(x)=-10x/(5x^2+5)^2

    Try again on the derivative. The second derivative should be:

    f''(x)=\frac{2x(x^2-3)}{5(x^2+1)^3}
