\begin{align*} y^{\prime }&=\frac {1}{x^{2}-16} \end{align*}

Solution by Maple

Time used: 0.001 (sec). Leaf size: 18

dsolve(diff(y(x),x)=1/(x^2-16),y(x), singsol=all)
 
\[ y = \frac {\ln \left (x -4\right )}{8}-\frac {\ln \left (x +4\right )}{8}+c_{1} \]

Solution by Mathematica

Time used: 0.005 (sec). Leaf size: 23

DSolve[D[y[x],x]==1/(x^2-16),y[x],x,IncludeSingularSolutions -> True]
 
\[ y(x)\to \int _1^x\frac {1}{K[1]^2-16}dK[1]+c_1 \]
