CAS Maple gives this as type [_linear]

\[ \boxed {y^{\prime }-\frac {x^{2} y-32}{-x^{2}+16}=32} \]

Solution by Maple

Time used: 0.0 (sec). Leaf size: 51

dsolve(diff(y(x),x)=(x^2*y(x)-32)/(16-x^2) + 32,y(x), singsol=all)
 

\[ y \left (x \right ) = \frac {-1440 \,{\mathrm e}^{-4-x} \left (x +4\right )^{2} \operatorname {expIntegral}_{1}\left (-4-x \right )+c_{1} \left (x +4\right )^{2} {\mathrm e}^{-x}+32 x^{2}-1696 x -7168}{\left (x -4\right )^{2}} \]

DSolve[y'[x]==(x^2*y[x]-32)/(16-x^2) + 32,y[x],x,IncludeSingularSolutions -> True]
 

\[ y(x)\to \frac {e^{-x-4} \left (1440 (x+4)^2 \operatorname {ExpIntegralEi}(x+4)+e^4 \left (32 e^x \left (x^2-53 x-224\right )+c_1 (x+4)^2\right )\right )}{(x-4)^2} \]
