CAS Maple gives this as type [_linear]

\[ \boxed {y^{\prime }-\frac {x y}{x^{2}-1}=2 x} \]

Solution by Maple

Time used: 0.0 (sec). Leaf size: 23

dsolve(diff(y(x),x)=2*x+x*y(x)/(x^2-1),y(x), singsol=all)
 

\[ y \left (x \right ) = 2 x^{2}-2+\sqrt {-1+x}\, \sqrt {1+x}\, c_{1} \]

Solution by Mathematica

Time used: 0.034 (sec). Leaf size: 24

DSolve[y'[x]==2*x+x*y[x]/(x^2-1),y[x],x,IncludeSingularSolutions -> True]
 

\[ y(x)\to 2 x^2+c_1 \sqrt {x^2-1}-2 \]
