comment Differential equation by series solution method: equating coefficients to zero
I think I got it. n=1,2,3.. and upwards already invoke n=0, which is set to 0. In other words, $2a_2$ is the coefficient of $x^0$, and we have to set coefficients of all powers of $x$ equal to zero.

comment How do you integrate $\int x(x+3)^ \left( 1/3 \right) dx$
The answer that I got, which is shown as correct is : $\frac{3}{7}(x+3)^{\frac{7}{3}}-\frac{9}{4} (x+3)^{\frac{4}{3}}$
